New information has surfaced regarding the apparent DDoS attacks involving TPU. As I suspected, TPU was not being targeted specifically. Rather, all known BF42 servers were being used to propagate an attack against one or more other servers. Because of the distributed nature of the attack, and the fact that BF42 servers were involved, many of the systems appearing to attack TPU were in fact just other BF42 servers being used by the attackers.

Unfortunately, given the nature of the Gamespy network protocols, we're unlikely to see an effective fix for this problem. The best we can do is to block the offending IP addresses as soon as we see them, so that's what I will continue to do.

According to the original source, the actual originating IP address of these attacks is 66.150.214.18.
