Looks like it's down again.. though again just forums.anandtech.com. The individual servers are still accessible. I can ping forums.anandtech.com too so the network is fine. Using other wget, I get a connection refused, which is the same response as a server not running anything on that port.
It seriously looks like a problem with the machine, and it seems to occur at roughly the same time each night.
Though I must say, it makes it faster for those that know how to get around it.
