HTTP Status Dogs (2011) (httpstatusdogs.com)

Thank you! I couldn't find it last time I needed it (it was on a Heroku domain that went https://http.cat/status/404 )

Also https://http.dog/

This one has much better choices for the images too.

Is this satire? If someone walks their dog past your office and you can see their testicles does someone have the job of blocking the view for all the employees?

I could see 206 being questionable as well.

How's the resource in question the dog? The dog's are used for illustrative purposes to convey a technical idea. So not finding a bone, the resource, is appropriate. Also it's such a HN thing to do to dissect humor in such a way.
