xkcd outage discussion

So it wasn't just my computer that wouldn't show explain xkcd? BobcatInABox (talk) 21:35, 12 September 2025 (UTC)

Also: what went wrong and how did they fix it? BobcatInABox (talk) 21:35, 12 September 2025 (UTC)

And: do we have a plan in case it happens again? BobcatInABox (talk) 21:35, 12 September 2025 (UTC)

It was clearly a server-side issue. (Well, more server-side than Cloudflare, which still covers a lot of ground.( There are a number of different things that could have been wrong, from the server rack-space no longer being paid for (a potentially more permanent death than the domain not being paid for - which we know has been, anyway) to someone having been messing about with the site and caused fatally excessive parsing errors (there's no sign of that, in the page-edit history that we see, although there's always a potential for the person who got the server working 'sensibly' again to have purged the evidence along with the problem).

Could also have just been a temporary power-outage/blown-fuse in the apartment of the person who currently lets the server hum away in the background (if that's the server's physical location, which I doubt) or that person was moving it from one residence to another and so obviously had to unplug it, transport it and plug it back in again to power and network connection (again, from what I know, I doubt that... but it's not an impossible scenario).

Unless we get to hear from whoever fixed the problem, we can just keep on guessing.

Assuming that any actual person did fix the problem rather than (for yet another theory...) it being a connectivity issue further along the chain that just happened to catch our server in that, and was just sorted out as a more general restorating of service.

I had several 'likely' ideas during the downtime... Well, obvious they couldn't all be actually likely, as they were mutually exclusive to each other, but a larger share of the divided percentages than some of the more out-there ones... but very little proof of any of them, now we're up and running again. Not ruled out, but without the basic fingerprints that I'd have expected to support their realities. And some of my imagined solutions to the outage were situations where I would not actually have expected the site to return at all, too, and these have obviously been defied/subverted given that we're now talking here about this.

The good news (with reservations, at least) is that, the way we've been returned to 'normality', this raises the chances of this issue not being a recurring one. With a side-line chance of if whatever-it-was recurs, it'll be solved far quicker next time. Whoever/whatever we have to thank for it.

The bad news is that I don't think anyone 'active' has anything to do with it (please do let us know, if you did!). Either no direct hands-on fix at all, as described, or someone who really doesn't want to bother talking to us users and only steps/stepped in for a bit of quiet background fixing that nobody'll properly appreciate. (My kind of person, that, actually. I rather like it when I fix issues so that nobody besides my more immediate colleagues knows they've been fixed... although ideally I'd be doing so before anyone even knew they needed fixing. And this wasn't my work, of course. With so little access, or even familiarity with the basic setup, you'd have to look elsewhere for any mysterious house-elf who sorted this one out.)

TL;DR; - I don't know how to answer your question. I get the idea that nobody will answer your question as long as anyone who knows doesn't want to. I don't eventhink there's any possible plan that we can devise to deal with it. Even with an 'off-wiki' forum to talk amongst ourselves about things, the next time this happens again. Even if we could agree on where to go, it'd just end up being a legacy chatroom (like the Euphoria one) once the inevitable day comes when something means that this site goes dark and never lights up again. C'est la vie, etc... 92.17.62.87 00:28, 13 September 2025 (UTC)

TLDR indeed. >"the apartment of the person who currently lets the server hum away in the background (if that's the server's physical location, which I doubt)" Elsewhere this year we learned of a forum which actually sat in the admin's garage. He had a health issue, weeks in hospital then months recovering at a relative's house. Forum went down. His #2 said he got some better and the forum came to life, but went down again. Life is like that. --PRR (talk) 02:48, 13 September 2025 (UTC)

I had noticed this issue too. I was actually drafting up an email to User:Davidy22 when I came back on here to get a screenshot and Cloudflare started working again! I had suspected that we were getting DDoSed, since Explain XKCD had some issues with that before and the server was clearly down across multiple devices and networks. Recent Changes also shows a 36+ hour gap between editing, confirming that the server was down across the board. I suggest that we coordinate some other form of communication so that we can share messages with each other and still have points of contact if this goes down. Jeff has proven himself to be flaky and unreliable, and I'm now treating everyday on here like it's my last.

This seems to be a recurring feature of many sites at the moment, whether behind Cloudflare or not. My suspicion is that scraping for AI is out of control, acting as a particularly stupid (vibe-coded) and well-funded DDoS. --81.96.108.67 06:58, 13 September 2025 (UTC)

Cloudflare was working on my error page. It looked like it was just the host server with a problem《プロキシ》(XKCD中毒者) 13:12, 14 September 2025 (UTC)

Comic discussion

La plume de la Terre est sous le bureau de mon oncle. BunsenH (talk) 21:33, 12 September 2025 (UTC)

I'm truly shocked that this comic (#3141) didn't have anything (obvious) to do with pi. 2603:3003:BCC:6200:FC4E:5757:BC86:E656 02:03, 13 September 2025 (UTC)

Off by 0.001 error. Or maybe Randall's sworn off pi/pee jokes. Perhaps we'll see when comic 3142 is released to the wild. 2605:59C8:160:DB08:925:A1C6:D2C8:428B 11:51, 13 September 2025 (UTC)

Only off by 0.001 if we're aware of the additional digits. I choose ignorance. 2603:3003:BCC:6200:98AA:C11E:AA31:F089 15:56, 13 September 2025 (UTC)

I assume those that manage this great resource for those of us that REALLY NEED xckd explained know comic 3139 got missed in the kerfuffle... 209.240.124.28 02:09, 13 September 2025 (UTC)

Using the ^{[citation needed]} tag FOUR times in a single explanation is not funny. ^{[citation needed]} These Are Not The Comments You Are Looking For (talk) 01:13, 14 September 2025 (UTC)

Counterpoint: Yes it is. Theclapp (talk) 19:25, 15 September 2025 (UTC)

Synthesis: It could be, but wasn't here. 82.13.184.33 08:30, 16 September 2025 (UTC)

My interpretation of the comic was that it was more of a satire on geology and how it interprets mantle plumes rather than just some random absurd thing. After all, looking at the Wikipedia page for mantle plumes, it lists like 10 totally random things that geologists sometimes attribute to mantle plumes. Qoiuoiuoiu (talk) 02:54, 14 September 2025 (UTC)

There is too much truth in this cartoon, see [1] to get an overview over the problems of the competing plume hypotheses. In short, yes geologists made up so many different plume models that this term has become either all-encompassing or meaningless. 87.180.165.87 07:38, 14 September 2025 (UTC)

I like that the title text seems to also suggest that Mantle should properly be pronounced Mega-antle 2001:1C05:71D:AB00:49C6:27F5:15E6:49C4 09:53, 14 September 2025 (UTC)

To my knowledge, D. B. isn't an "alias" of the plane hijacker but more of a cultural nickname. The hijacker named himself "Dan Cooper" (an European comic about a pilot. Relevancy never proved or disproved by the FBI according to Wikipedia) while D. B. Cooper was a random person misnamed by the media? 91.181.199.112 (talk) 12:12, 15 September 2025 (UTC) (please sign your comments with ~~~~)

Yep, D.B. Cooper is a nickname given by a reporter that stuck, after the composite drawing was released. But back to the comic, this case could have been made much harder in 1980 due to a mantle plume. LOTS of stuff got buried under ash in the Mt. St. Helens eruption in May of 1980.Seebert (talk) 15:47, 15 September 2025 (UTC)

Forgive me if I'm off base here, but isn't this one a joke about Dark Matter? 12:54, 15 September 2025 (UTC) It seems like a Dark Matter joke to me too 136.62.202.91 18:18, 15 September 2025 (UTC)

He did this whole comic just so he could do the "antle plumes" pun in the title text, didn't he? Theclapp (talk) 19:25, 15 September 2025 (UTC)

I am a bit surprised of the passive/agressive tone of this explanation. Is it simply me not being good enough in english ? 66.159.217.128 (talk) 14:49, 16 September 2025 (please sign your comments with ~~~~)

It makes no sense to put [citation needed] on something being unconfirmed. Either say that mantle plumes have no shadow aspect[citation needed] or just leave it as being unconfirmed without the need for citation. Kapten-N (talk) 14:19, 6 October 2025 (UTC)

I'm not sure if that was even meant as a [Citation needed] (tongue-in-cheek, for humour) or [Actual citation needed] (the real thing), at least as far as whatever the tag is attached to. I'd be tempted to remove that and/or reword the text to make the intended serious/funny sense more obvious. 81.179.195.93 18:58, 6 October 2025 (UTC)
