The message was an old one from back when TFL was moving servers. The message has been fixed. It's a 50x error page, triggered either when there's some (unusual) server error, or when you request a lot of php pages in a short amount of time. If that page weren't there, you'd get a pure text, and more cryptic, 50x error message instead.
The "fictitious character's site" happens to be youtube. It's an embedded youtube video.
