Saturday grid glitches [updated]

Something seems to be up on the Second Life grid this-morning. For the last half hour or so, we've been getting increasing numbers of reports of unusual group IM and teleport problems, and simulators losing communication with each-other for a minute or two at a time(though neither one has restarted or crashed, as they lose communication it gives that appearance).

No word from Linden Lab about the issues this-morning so far (5:15AM SLT — US Pacific time), but it is certainly causing users some trouble. Watching several sims repeatedly losing and regaining communications with each-other over a fifteen minute period — well, this is a behavior pattern (or failure mode, if you prefer) of the grid simulators that we haven't seen before.

Update 5:57AM SLT (US Pacific time): Linden Lab have now posted a report of their own and say that they know what the problem is, and that they at least have it contained, and are working to bring things under control.
