Consistent 90002 and 90006 errors: possible DDoS?

[Gyson]

I am *not* using Comcast and can't stay connected tonight. It's not just this game either, although it is not every game (I'm not having problems with Guild Wars 2, for example, but can't stay connected with a friend on TeamSpeak).

Problem started around 6 PM eastern time. Everything was normal smoothness prior to that; the change was rather abrupt.

I don't think it's necessarily ISP specific, but more dependent on the route your traffic is taking. As others have noted everything seems to start falling apart on the gin.ntt.net hops.
