NOTICE: WUWT to begin migration to new cloud server – opening up new horizons

Hello everybody,

I wanted to take this opportunity to thank everyone for their continued patronage of WUWT, and to let you know that in the last couples of months the site has been under attack by a variety of forces, which has reduced the viability and visibility of the website. After consulting with technical people they have graciously offered to help me and we’re in the process of beginning a site migration. It is a daunting task, as there are over 18,500 articles and 2.6 million comments. In addition to that there’s about 13 GB of image files that are indexed to specific articles. At present, WUWT stands at 353 million views.

In the short term this migration may mean some interruptions of service, in the long-term this should ensure that WUWT continues to reach audiences worldwide without interruption or interception by some of the nefarious forces that operate from the shadows trying to reduce the impact this website has. It will also toughen the site against attacks.

Over the next day the process of migration will begin. If I am lucky, there will be very little interruption of service. However as these things go sometimes it’s not always hiccup free, and the chance of the site becoming unreachable for awhile while DNS cache is cleared. However, the technical engineers at WordPress seem to think it will go okay.

I hope I don’t have to put up this test card 😉

Another long-term benefit of this migration to a new server is that it will remove some of the limitations I’ve had by being hosted on Instead I’m going to be hosted on the same cloud server group that hosts many of the largest news websites on the planet. All of this will still be under the control of the people at WordPress, but the good news is that in the nearly 12 years I’ve been doing this, WordPress as a company has staunchly defended my right to publish articles which they have undoubtedly taken some flak for. There is a back story from 2009 related to Climategate, Al Gore, and Google that I believe I’ve shared in the past to give you an idea of the kinds of things I’m up against.

The other good news is that being on this new server group it will give me freedom to install plug-ins that I could not do before. This will enhance our ability to make conversation and commenting run a little bit smoother, in addition to offering some other features I could not offer before. Guest authorship of articles will also benefit from this change.

Thank you for your patience during this process, and most of all thank you the readers, the moderators,the contributors, and even my detractors for making WUWT the most viewed climate related website on the planet.

I’ll post an update again once the process is complete.

Thank you!!!!


Just to let you know, Google Chrome has been blocking me from accessing your site all day, since early this morning. Claiming “unsafe,” and that your “certificate” is unverified. Wondering if this is because I left a couple of comments over the past several days. Wouldn’t be surprised at all if you (and by extension, your visitors) are under attack by the Usual Suspects. Writing this now in spite of taskbar saying “Not Secure.”

Matheus Carvalho

I tried with Opera (nowadays a mere clone of Chrome), and it was the same. Very strange! I could access using IE.


Managed access with Opera [old version] but refused by Safari


Safari says it can not open page becase it can not access a secure connection to server.


Happened to me too.


Safari works OK here in northern NY at 8:55 am, 5/30.


I was unable to access for several hours. You’re up now. What a relief!

The time given for the comments is off. I’m in the same time zone as Anthony, which I’ve always found quite convenient, and the time is now in the future. Will this be corrected?

Also, I noticed we can no longer rate articles with 1-5 stars. Is this permanent?


Appears to be Greenwich time. Probably a default setting.


I’m using Firefox and can’t access some things (links to old pieces). I’m in Australia.


I was unable to connect to WUWT with Firefox due to “unsecure connection” on Monday. I used IE and it was fine.


It was the same on Bing for me.


Site loads on my Pale Moon (Firefox fork) without hiccups, though haven’t tried to access any old content.

Try adjusting/disabling security features on other browsers. I recently had to level down Pale Moon’s blocklist when the devs added NoScript to it. >:( Because it breaks sites, they said. No duh.

Dr. S. Jeevananda Reddy

yes, it is same with me

S. J. Reddy


I have DuckDuckGo in my extensions…. Runs on Google, but uses DuckDuckGo search Algorithms.

Giles Bointon

I use DuckDuckGo and I love the way the page appears to ‘burn off’ past searches to leave less traceable history.
As an aside, can anyone give me good articles re the current status of Tha Arctic and the Antarctic, I’ve taken on a fanatical greenie on the Guardian of all places!

Thomas Finegan

My computer tells me Edge is safer than Chrome every few days, HA!

John P Schneider

I had that problem frequently when I had McAfee. Changed to defender, and the problem disappeared. The ‘Unsafe” tag seems to be the result of user input. So, folks who don’t like WUWT basically marked it unsafe under different emails until the app (McAfee decided they must be right.
I found lots of conservative websites to be similarly blocked.

Moderator and Anthony FYI;

New posts are correctly accessed, for example:

Recent older posts just access the article, not the post, for example
just accesses the top-of-page of the article, whereas
now correctly accesses the post.

Not a huge problem, but old references to previous posts will no longer work unless this can be fixed.


Do we know enough about clouds to risk this.

David c Grubb

Good One!

Harry Passfield

Real clouds have an albedo effect; AGW blog clouds have an ‘algorebo’ effect.
Best of luck, Anthony. Please don’t end up like – which has been pretty much silenced after 20 years.

David A Smith

I’ve looked at servers from both sides now.
PC and mainframe
But still somehow
Its DOS attacks I recall
I really don’t know servers at all.

RobertBobbert GDQ

Are you trying to …Cloud…the issue?




Hmmm…. I have a rather old computer, practically an antique. Still runs well, but I will have to take the old thing off the net some day and I know it.
I have never, ever had any trouble finding WUWT, maybe because I type in the entire name of the site instead of just WUWT. Specificity counts in something like this.
I am, after all, still operating on Windows XP and have stubbornly refused to change that because it works fine. But on the other hand, my 2003 machine limited in space on its hard drive, and I will have to get a newer machine with more room and a faster response just to keep up.
I have a blog, but I can’t see anything on it it through WordPress’s changes to their format. I have to go in through a back door to access it. Otherwise, i would not bother with even thinking about a new machine.
I can’t keep up with this stuff any more… and I can remember when surfing the net was such a big deal that you could be up all night on Friday, finding stuff… and now, it’s the biggest waste of time ever unless you are very specific about what you want to find.


Sara, you just earned a virtual thumbs up. All operating systems after XP are glorified code bloat, for the sake of reinventing the wheel and sales revenue per quarter.

The MS interfaces and their funtionality are also much less intuitive or confidence-inspiring now, imho. All hat, no cattle.


MS is still dazzled by the ghost of Steve Jobs and wants more and more to Apple-ify their software, to the detriment of their own brand.

I have Windows 7 on my current system. In the roughly 2 years I’ve used it, I’ve gotten only one BSOD. And that one was on me, from fiddling with some unstable emulation software.


I’m no techie but I’ve been using Ubuntu Linux for years, currently as Lubuntu. Easy to use and customisable. Also free.


Sara, is same here with 2002 Dell Win XP upgraded to sp3. You didn’t say what browser used but I went to Firefox 52.6.0 ESR (Extended Service Release) which is the last upgrade made for XP and available from Firefox. Also upgraded the Dell with a much larger 500 gig IDE drive and then cloned the old drive onto the new one using clone software from internet. Have a very obsolete Sony 20 inch CRT monitor that still works everyday (have tried a couple of LCD’s but they had less small letter/pixel definition, maybe my video driver/don’t know). New IDE drives are still available at Amazon and inexpensive.


I think my last MSN browser upgrade a few years ago was IE 10, not sure, but I got the message ‘can’t go any higher’. Now I get messages from Google that my hardware is too old and I won’t get any more Chrome updates.
Well, next year, after I get new front steps and a new kitchen cabinet and a couple of other things done/fixed first – next year, I will get a newer computer and it had better be as sturdy and reliable as this one has been.
If it ain’t broker, don’t fix it. If it still runs and you can fill the tank, drive it.

David Spain

I have an old computer. I don’t know how old, but it is beige. Is that old?


Is it a desktop or a laptop? Either way, yes.

Clyde Spencer

We can parameterize the clouds and everything will work fine. Trust me!


Clyde Spencer
In other words, every cloud has a silver lining.
Yes, I’ll go with that, even the climate change cloud hanging over us like the sword of Damocles.
Chock full of opportunities.


… WUWT the most viewed climate related website on the planet.

Given Google’s global warming search bias that is an amazing accomplishment. Congratulations sir.

Except, virtually every search for things climate, especially topic with religious consensus beliefs, links to undependable consensus sites and climate politics sites overwhelm the response links.
An odd occurrence, given their very low internet views and stats.
Liberal elitist billionaires, apparently, can buy fake popularity for their propaganda sites.



e-bulletin, Issue 72, June 2009

Topics include: to green the internet with “.eco”

Good luck!


You do the world a great service and I have learned a great deal. Thankyou very much

Ken Mitchell

Good luck in the conversion!

J Mac

“Migration to a new Cloud….” – It sounds so diaphanous and airy!
Looking forward to the new capabilities and Thanks (!) for doing what you do soooo well, Anthony!

Alan Tomalty

A suggestion is to allow searching of previous articles when you are on the site. As it stands now one has to search previous articles by Google


I think it’s a positive … we all know that CAGW proponents do not handle clouds well …

Anthony ==> Best of Luck with this. See ya on the other side. Kip

John Ledger

Thanks for the update Anthony, and good luck for a smooth transition. WUWT helps maintain our sanity in this corner of Africa where infectious Carbonophobia, spreading rapidly and profitably among the ruling class, is resulting in the proliferation of ghastly industrial wind parks that are blighting some of our most beautiful and scenic landscapes, as well as killing a wide variety of birds, including endangered and migratory species. We are heading down the same path as South Australia, and nobody, except a few perceptive commentators, seem to be concerned in any way. The wind industry, government ministers, and media morons clap their hands and ululate with joy at the billions of dollars of investment flowing into intermittent wind generation plants. They either do not know, or chose not to share the ugly secret that probably 65% of this investment goes straight to Germany, or Denmark, or somewhere else, to pay for the machinery and the towers. The Germans and the Danes have also been very, very helpful to South Africa in funding research and propaganda to promote the wonders of wind energy. They are laughing all the way to the bank.


Bryan A

New Cloud…Hop aboard your Golden Nimbus and Fly away. A few interruptions can be handled if need be.
Hopefully the transformation goes smoothly.

Hello Anthony – I will be there come rain or come shine…


Who are the ”nefarious forces’ you refer to?


My guess is the Deep State and B Husssein’s shadow government.

Sounds well planned. Good that WordPress is so supportive. Gluck auf!

Tom Halla

Good luck with the changeover.

William Astley

Sound great. Best wishes on the change over. This is a great site.

Terry Gednalske

Anthony, good luck with the transition, and thank you for making WUWT available to us all!


Time to break out the Joni Mitchell: I’ve looked at clouds from both sides now
From up and down and still somehow
It’s cloud’s illusions I recall
I really don’t know clouds at all…



F. Ross

Sounds like a good move to me, Anthony.
Will be checking back on my usual daily basis.

Roy Denio

Cloud is fine, but more costly than VPS with Solid State HDs.


so,…migrating from linux sercer(s) on amazon aws to your own aws instance.
hope you have good server admin


I haven’t noticed any problems reaching this site and I often look at it several times per day. I have seen some of my comments disappear though, and that’s frustrating.


How many “Hiroshima bombs” will the cloud consume?


Go Go comment preview and editing!


Excellent news

Terrific news, Anthony!!
Whenever software vendors swore that users wouldn’t notice upgrade(s) installation, that always meant long weekend hours, workarounds and angry superiors.

Steve in Seattle

Good … and Thank you !


google currently is blocking wuwt as a dangerous app/site and is asking for more info. switched to Bing

Jon the technologist

google is currently blocking WUWT as a dangerous site/app with no privacy and asking for system info and page content. Switched to Bing


What exactly is Google’s warning message?

Paul Johnson

Microsoft Edge is giving me a “Certificate Error” when trying to access the site.


WUWT just came up as the site being insecure, and so Firefox refused to load your page as did Chrome. I was able to load WUWT on Chrome anyway by allowing despite the danger. Firefox still will not load your page, What is this all about?




Just happened to me as well, was ob site reading this post 3 hours before with no issue. Just checked to see what was new and got the same warning on Chrome.


Chromebook just says what it always says about the site being insecure because “attackers might be able to see the images you are looking at and trick you by modifying them ” It does not go any further.


This is because some images are served over insecure HTTP; an adversary would be able to change these. This is a risk on an high value site (like finance), not so much here.


Here is part of the message why from Firefox ================================================== Unable to communicate securely with peer: requested domain name does not match the server’s certificate. HTTP Strict Transport Security: true HTTP Public Key Pinning: false


Never mind, I just read this post which explains what has happened. Look forward to when this is over.


Me too. Firefox absolutely refuses to load WUWT.

Right now I’m using Dillo, a really simple browser that doesn’t understand the smart things required to create a security problem.


“Firefox absolutely refuses to load WUWT.”

What is the complete error message?


Is there some way that us lowly users of these nefarious browsers can get back at them for sending us pop-up windows that falsely warn us that WUWT is a dangerous site?


“falsely warn us that WUWT is a dangerous site”

Did they really? What was the EXACT warning message?


Hopefully it is a “reign” cloud!

This is great News. Thank you!

Ted Clayton

The WordPress VIP, and their Enterprise Cloud not only earn them money, but gives them a stake in your success & well-being. WordPress loves nothing better than to host well-known ‘fair-game’ like WUWT.

When the tech-rep from NYT comes to WP with a security concern, and buttonholes the WP-rep on assurances, they can respond with “You know that What’s Up With That climate site? Yeah … you think you got security-concerns…”

After you can pass the basic Security Quiz, your next step is Live Ammo & Concertina Wire. They’re drooling at the thought of WUWT on their cloud. What an ‘Ad’ for other Enterprise customers…

Anthony Watts & Crew,

Are you delving into the new Project Gutenberg block-editor? Lots of questions in the community, on just Why (really) and to what aim. My assumption is, Matt Mullenweg is up to something big, and the block-editor is a means to the end … which remains secret for the time.

Not really much question, ‘What it is’. I gave “phpWebSite” an extended try, before WP came out. It’s an Academic project, and it was all block-structured & Edited. I liked it, but the project was not receiving focused on-going attention (and still isn’t; parked on GitHub now). But it was a great experience.

My guess is, the WordPress dotCOM biz will continue as-is. This should impact mainly the dotORG scene.

Plugins are the opioid of the dotORG crowd. 55K titles & counting…


Also unable to access site via Chrome but succeeded with Firefox – for now. Chrome have a message stating-

“Your connection is not private
Attackers might be trying to steal your information from (for example, passwords, messages, or credit cards). Learn more
Automatically send some system information and page content to Google to help detect dangerous apps and sites. Privacy policy”

When you clock on the underlined “system information and page content”, it takes you to a long page of general blurb where there’s an invitation to email them via Entourage. Is this censorship, or merely to do with your new site???


I got a similar message from the noscript addon I use in Firefox. I didn’t need to change noscript settings though, at all, I just had to empty all the privacy settings, are restart, then Firefox and WUWT came up, no further problems.

Was most likely just the old cookie that needed binning, but I flushed the lot anyway.

Takeoff and nuke it from orbit I say, you’ve gotta be sure …



It’s: Common name invalid in certificate

It just means that the Web server presented the wrong certificate to the navigator, and the navigator cannot authenticate the Web server via encryption, so the access is blocked.

This is expected behavior when the name in the URL doesn’t match either names in the certificate: the common name (“CN”) or some alternative name (subjectAltName).

Currently the certificate contains:

CN =

subjectAltName extension:


Had to go to my Vivaldi Web browser, as Firefox denied me access to your site with no way to access it with their new security settings (since version 59). At least, Vivaldi allows me to, if I trust the site, go ahead and load it. That was the only way I could access your site to find out what was going on, during the transition.


Same occurred to me, I emptied all the privacy settings options, such as cookies, active logins, cache, etc., and restarted and the new WUWT came up in Firefox.

Leo Smith

hmm. lets see what this looks like as seems to be on the new site


Thank you so much Anthony, hope all goes smoothly. The net would be a monochromatic and depleted place without choice sites like WUWT.


@ site designers and Anthony,

It would be nice to have an Up-Arrow button, after you’ve commented, to take you up to the top of the page again, as it’s a pain scrolling up again with a touch screen. If possible. Cheers.

Len Jay

My heart sank as I clicked on my favourite website this morning that it was not available. “Oh no”‘ I thought, ” the New World Orderers had got to WUWT at last”. Fortunately this was not the case but it got me thinking to sometime back in 2016 when I was watching a video featuring presidential hopeful Hilary Clinton and Mr. Al Gore, who was endorsing her for president. At that time a cyclone was off the Florida coast and was threatening to cross the coast and devastate the State. It was, he explained, all due to global warming implying, but not admittedly explicitly that it was my fault because I had opened a can of lemonade in Australia and let the carbon dioxide escape, and thus the impending disaster in Florida!! However all would turn out well, the cyclone would continue to move seaward to the coast, and no further threats would ensue if only the American public would vote for Hilary, and I didn’t open any more cans of lemonade. Throughout this Mrs Clinton was nodding wisely like a dashboard bobblehead. My despondence generated in me by watching this video evaporated into thin air much like my lemonade gas when shortly after I lucked onto WUWT. It was the opening up of a new world, and I have been so grateful to Mr. Watts ever since. Thank you Anthony.

Eyal Porat

Wow, you came here late!
Had the great fortune of finding WUWT in 2007.

C. Paul Barreira

The font, one that many use, is barely legible. Pity.


I have had no problem getting to the website via Google, WUWT is my first port of call each morning.#
I find it both interesting and informative, and feel immensely grateful to Anthony and his team for their hard work in keeping it going.
That said, I agree with C. Paul Barreira’s comment, as older eyes find it difficult to read the small print. This seems to be common in many magazines nowadays, presumably to save ink, but this doesn’t apply to digital media. I had no problem with the previous font.
There is also a trend in magazines to use coloured print on top of colour photographs which can made it unreadable where the colours are the same.


Does your browser have a zoom function? Readability is fine in Pale Moon when I zoom in a few times. It’s not like a magnifier, it actually increases the font size.

Eyal Porat

I was looking for the Tip Jar but could not find it.
Any way to pass donations?

mark harvey


Excellent idea, and many,many, thanks for the sanity of the site.

Of interest, I had no problems finding the site on my imac, using Firefox. Checked on the W10 laptop and MSEdge went straight to the site.

Hope [desperately] that it all goes well.


There is a back story from 2009 related to Climategate, Al Gore, and Google that I believe I’ve shared in the past to give you an idea of the kinds of things I’m up against.

Thanks for the link to cfact. Interesting observations and opinions there. I’ve also noticed the totally disproportionate Google search rating of desmogblog, rationalwiki, and even hotwhopper. But, some people like those, and probably that’s at least partly behind rating. It just turns very bad when Ph.D Joe-average suddenly finds himself smeared at those hate speech sites. You have to have some guts to be against the green mafia in academia.


opened immediately as usual for me using xp n firefox in aus this evening;-)
CME might upset clouds a tad more?
enjoying the larger brighter page n print
keep up the great work Anth*ny n mods;-)
