Back when we were discussing site design, @Jin came up with this design question and we do have some answers which could be relevant to our 404 page.

I think we need to get something defined, as ours are very bland.

Bicycles have this for their 404:

Which I think is wonderful.

We are using an SEI standard Captcha page (HAL) and we have the laptop/token Error page but we need a 404.

Laptop workstation, no dock, with cables, with security cable, with no laptop.

Maybe I should just take a photo?

Or maybe a server missing from a rack would be even more obvious. Ooh, and empty equipment rack with all the cabling in place. Score.

That one will take some work. Anybody have access to a datacenter with some scheduled maintenance?

  • If you provide the photo, we can put it on the page for you. Just make sure it conveys "not found." All of your examples seem to, but some of the ones below -- while funny -- do not.

Bike inadequately locked up

@WesleyDavid posted this in the ServerFault chat room and I thought it might fit well here.

People are not very good at locking up bikes.

These have potential too, maybe for the 429 Too Many Requests response or 413 Request Entity Too Large:

How about specialized "honeypot" 404's for web.config, :$Data, or app.mdb (etc)

  • Nah, this is an access violation - not an availability issue. (Though, with the proper tools, it could become one.)

  • @Gilles Hence I wrote that the last line better be re-phrased. I know it would cause a controversy otherwise :)
