Buddylist updates off
Buddylist updates remain deactivated.
Comment: there seems to be an instability of the XMPP cluster under the condition of a combined high load of Web and XMPP. This is a special case, but we prefer to keep buddy list updates disabled until the condition is fixed, rather than risking general XMPP operation.

Load Problems
We are experiencing high load. This results in very slow Web access and even XMPP cluster failure.
Stopping some sub systems, e.g. buddylist updates, topcloud.
Comment: most developers are working on optimizations. We are getting new all time highs every day and we are trying to keep up with the growth. This is an ongoing process.
