It's an actual redirect- if you look quickly, before the redirect, there's a page titled "Your Page Title," with the text "Optional page text here." If you press Control + U quickly enough (at least in Firefox), the source code comes up. It is:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
Your Page Title
Optional page text here.
Odd. The redirect was coming from LW? o_O
http://lesswrong.com is suddenly redirecting to a Tibetan meditation site. What the hell?
