# AddType text/html .ps

301 Moved Permanently
Erik Demaine's webpage
has moved to a new server.
The page you were referring to now has URL
%s.
On most browsers, you will be brought there in 10 seconds.
Please change your links, because the old server will go down in a couple
of months.
(Otherwise I would have used a true 301/RedirectPermanent.)
Thanks! - Erik
