I can get to the grey, but not the blue or green. I get "400 Bad Request", also:
Your browser sent a request that this server couldn't understand.
Size of a request header field exceeds server limit.
Apache Server at www.metafilter.com Port 80
I also can't connect to status.metafilter.com. Can't use contact form either.
This has been going on for the last 15 or 20 minutes or so.
