Since the 3.3.3 changes to apparantly fix some networking issues, I found myself instead suffering from even worse latency and during the last few days particularly with increasing disconnections.
Running PingPlotter to get traceroutes over a period of time, I am noticing varying delays different hops, and packet loss.
Neither of which always occur at the same point, anything from my ISP, to telia (who seem to operate some of the blizzard networking infrastructure), to anywhere in between.
Any suggestions would be appreciated, since the usual diagnostics are not pointing to any one cause.
