FWIW, based on comparing notes with folks in my FC, everyone who had the terrible connection problems was on Comcast. Those of us not on Comcast—on Verizon or Qwest or CenturyLink or whatever—were all fine. Moreover, one who connected via a performance gaming VPN was fine through _that_ since they were coming out of a non-Comcast address on the other side of the VPN.

I suspect there's a boundary router between Comcast and NTT upstream from the servers that's gone haywire.
