Happy 404 Day. Whats your favorite 404 error page?

Financial Times has my favourite: https://www.ft.com/404

A range of spurious economic explanations for why they couldn't serve the page.

https://www.thesistersofmercy.com/error404page.html (written by Andrew Eldritch himself, like the whole site!)

Also:

  Once upon a midnight dreary, while I pron surfed, weak and weary, 
  Over many a strange and spurious site of 'hot xxx galore',
  While I clicked my fav'rite bookmark, suddenly there came a warning,
  And my heart was filled with mourning, mourning for my dear amour.
  "’Tis not possible!", I muttered, "give me back my free hardcore!"
  
  Quoth the server, 404

Adult Swim's 404 page always has a dark, sometimes surreal, shaggy-dog story that ends with a reference to the page being 404.[1]

The page seems to return the same story each time you access it (at least on the same day). I'm not sure when they change from one story to another. The author has posted some of the other stories on other sites.[2][3][4][5] I still vividly recall reading this one in particular (although this reproduction is missing the bolding of the text in the second to last paragraph).[6]

I'm surprised that the "!!1" title on https://google.com/404 has survived so long without some manager making it more corporate.

Slack's 404 page (https://slack.com/404) is a throwback to Glitch, the MMO game that its founders pivoted from.

NPR's is one of my favorites: https://www.npr.org/404

Here's mine https://sivu.jp/404

I do particularly enjoy Amazon's https://www.amazon.com/404

Someone else mentioned Github which is always funny until you realized you followed a bad link to a repo you were looking for.

Thingiverse has a great one when you can force it to happen: https://www.thingiverse.com/nonexistant404page/designs

404 pages should have a different favicon so that when opening multiple tabs in the background you will notice something different. Here's mine with a little easter egg when hovering over the numbers: https://ss64.com/404

I'm going to ask a stupid question at my own peril.. please go easy on me

Does serving a 404 page still allow the response of 404 as the response code? or is it technically a 200 since it is serving the custom 404 page successfully?

I'm a fan of this 404 page of dancing construction workers. I think the original page got taken down, but it's available on YouTube:

My favorite and most creative 404 page I saw is for ROOT CERN software *

https://root.cern/404/

It is the error you wish was true in your life.

* Used as C++ interpreter with devilish syntax to help physicists do data analysis.

I love the World of Spectrum 404 page [1], which had a mention here last week [2].

IMDb has random movie quotes: https://www.imdb.com/404

I somehow took a liking to this one, really simple and a bit funny as Anthony is the patron saint of lost things. https://diopitt.org/404

Shared here a few days ago (and not by me - I'm stealing someone else's stuff here): https://www.ft.com/errors/page/404

I like the Norwegian Army's: https://www.forsvaret.no/en/404 The version in Norwegian language looks more like a bullet hole for some reason: https://www.forsvaret.no/404

https://http.cat/404

http.cat is one of my favorite resources. I get to find out what the status code means and see a cute cat.

Darn storm troopers can't find a droid to save their life.

I really like the one from gamespot: https://www.gamespot.com/404/

I like the slider puzzle Mercury built into their 404 page:

My high score today is 33.

My poetry site's 404 - you get presented with a randomly selected poem as an apology. You can refresh the page to read different random poems. If you refresh too many times your eyes will bleed. You're welcome!

https://rikverse2020.rikweb.org.uk/404

I think it's a missed opportunity that Roland doesn't have a https://www.roland.com/global/products/sp-404mk2/ on their 404 page.

I used to frequent a site titled "The Best 404 Page Ever" that played a random flash file on refresh.

Seems like someone's recreated it here https://thebest404pageeverredux.com/

Moparisthebest's 404 where the web server has an existential crisis: https://www.moparisthebest.com/404

Cleaned up some of the spelling and grammar and took this for my own site :)

Still this old classic: https://github.com/abc/xyz

I always really liked this one, now no longer in the original place after that site shut down:

https://doubleyoudoubledoubleewe.www.dash.deeohhtee.dash-das...

There are longer versions of that variant of the poem, and versions with cleaner references, that can be easily found, but I think this is the original – it is certainly the first instance of it that I saw.

Not an actual 404 error page, but: for a short while, I ran the web site for an Amnesty International writing group in the Netherlands. We were assigned group number 404. The home page had a similar layout to the standard 404 error message but with a text like "Error 404: person not found", and a link to the actual home page. Let's just say people were confused and didn't find us.

At least I had fun.

My own 404 page has served me well for years https://steviep.xyz/404

https://www.wendys.com/404

Wendys has a video game, it's amusing.

Pretty intense https://www.tabletmag.com/404

Ahrefs https://ahrefs.com/404

I enjoyed the new SuperMega website's 90s web styling, including their 404 page: https://funnybrothers.com/foobar

The hit counter is my favorite part.

I love creative 404 pages! My favs are the ones with mini games. https://www.kualo.co.uk/404 has a Space Invader game and https://nouveller.com/404/ has an old school desktop with Jurassic Park references.

I actually did a whole roundup of creative 404 pages at a previous job: https://webflow.com/blog/best-404-pages

Taco Bell's has always made me laugh. The taco's face in the split second before falling on its face kills me.

Bravoboard's 404 Page - https://www.bravoboard.xyz/404

Bravoboard's 404 page is truly unique and innovative! It features an interactive message board where visitors can see posts and messages left by others, inviting them to join in and leave a message themselves. This creative approach to a typically mundane page highlights Bravoboard's core capabilities in a fun and engaging way. Bravo to Bravoboard for such a clever idea!

Back around 1996, MIT had this haiku as their 404 page:

I ate your Web page.

Forgive me. It was juicy

And tart on my tongue.

I wish I could find a copy of the old reddit 404, but the current one is still pretty good:

Ironically if you try https://www.reddit.com/404, that actually resolves because it takes you to the post with that ID. :)

I didn’t know there’s something called 404 day, yesterday I was designing a 404 page for my startup site, front end isn’t my area of expertise and not yet done but open for feedback https://ubiquitous-tapioca-350c21.netlify.app/404.html

I wonder how many admins/devops/whatever will get alarmed by an inexplicable bump in 404s served thanks to this post :)

I enjoyed The Australian's. Fake quotes from various Australian politicians about the missing page.

It's been around for a while, and I'm plesently surprised it seems like they've still been updating it.

"maybe go try some wasabi pea dust ice cream."

I can't recreate the error now, but going to www.moosejaw.com in the EU used to give me the error "we can't offer products in EU... We're working on it. but until then, maybe go try some wasabi pea dust ice cream." I have a screenshot, thank god.

Dribbbles been one of my favs for a long time. Color slider that arranges Dribble shots into a 404 that match your color selection

RTÉ (Ireland’s national broadcaster) has a 404 page with a nostalgic touch for anyone who grew up here in the 1980s: https://www.rte.ie/404

The original Flash version of https://homestarrunner.com/404

Even though the sound doesn't play anymore, you can still hear it in your head.

Today though, definitely not proud, just too lazy to change it :)

I like the design of Heinz's 404 page. Mostly because of the clever use of ketchup in the design. https://www.heinz.com/404

I think that this video, embedded in a 404 page, makes the best 404 page, hands down: https://www.youtube.com/watch?v=7dYKEMSMV3w. Lance Cummins created this video 10 years ago rewriting the words to U2's song "I Still Haven't Found What I'm Looking For". The words start out: "You have come, to my site. You were hoping, it would be alright, only to find this page, only to find this page. You can yell, you can scream, throw your keyboard, at the computer screen... The videography here is really excellent.
