Played Sunday 18th, Tuesday 20th, and Wed 21st of November between 8PM and 10PM, and 7AM to 8AM (AEST, GMT+10)
Latency was 90% stable at 280ms; occasional jumps to yellow which lasted for a few minutes.
Rubberbanding was quite frequent. Mostly noticed yesterday when my latency showed green, but I began a fight in Act 2 with some Elite dude... the screen paused, then jittered, then fast forwarded to show me my death.
I can't pin point anything helpful, unfortunately, as to what/why it is happening. It just seems quite random, but annoyingly frequent.
Something to consider before starting a hardcore character, that's for sure. Or just see it as something that adds to the difficulties of hardcore. :)
