FYI if you live on the East Coast and only had ping spikes this weekend, chances are it's not yours or blizz's fault for once; a major routing hub was experiencing major major latency issues and everyone going through it, cable or not, had a permanent 400-600+ ms latency, it was at it's worst yesterday. Wasted my sunday lvling pretty much, I ended up just playing Oblivion all day instead lol; I dunno if they fixed it yet but my tracerts no longer go through that bad hop today but I haven't been ingame yet to test
