Static1.robohash.com goes through the CDN.. If you load a PNG through there, it's cached. I wouldn't do the whole site through there, though, or you'll get the CDN's IP!

i figured it was something like that but i felt i should mention it just in case.

your concept did a good job in alerting me that the IP that was supposed to me mine was not :)
