We currently plan to have an update ready for next week. It will include fixes which should result in less game server and community server crashes that are responsible for the groups/raids disbanding and latency issues. Pending testing we will announce the downtime for the update early next week.

As a reminder: make sure you don't miss the free weekly item packages which will start to be available on 5th of February. Each week during February there will be a different free item package available which can be claimed once per character.
