same, it seemed to happen for a short while a few hours before then too. I couldn't access anything for ~10-20 min (grey screen) and then everything was fine for the next few hours. At first i thought it was a DNS issue, but I changed to google DNS and it was was still showing a gray screen. I guess it wasn't very much like a DNS error though, since there was no problem finding anandtech, maybe it was a vbulletin thing? Cause it was the same gray default background.
Also, VirtualLarry's avatar is pretty appropriate for this
