Happened to me 10pm-ish. Using Gametune proxy which was smooth all the while. Suddenly keep getting dc. Gametune owner says might be TMNet doing some rerouting screwing up the presets on his servers.

The last time this happened late last year I had to switch from beloved 60.50 Streamyx IP which suddenly became crappy and changed to 60.52 which suddenly became the best overnight.
