For some reason, I like error pages. So I'm going to put some ones I've found on here.
I think this is a 404 error for Akamai NetStorage, since I checked the server on developer tools and it said Akamai NetStorage (the text on the page is quite small, it says "Not Found").
I also found this other error that says "Not a file". It doesn't have a server response header, but it looks similar to the Not Found one I saw, so I assume that it's still Akamai NetStorage. This was also on the same website, and I just deleted the file path from it.
