Always boom tomorrow - Second Life update aborted and rescheduled

Today's attempt at an updates and a patch rollout in Second Life went really rather badly, with mass login failures and other unexpected side-effects during the preparatory phase. The Second Life grid didn't entirely shut down, but it was a near thing and the status page claimed (erroneously) that it actually did.

"At around 11am, an issue that didn't show up in testing appeared which stopped the "login" servers from talking to the "presence" servers. Unfortunately, it also interfered with our monitoring systems"

Linden Lab says that they're still trying to track down what caused the communications failure between systems, and are tentatively going to try to reschedule the same update for tomorrow, assuming they can isolate and fix the problem. The schedule will most likely be the same as the last one, with preparatory upgrades at around 10AM SLT (US Pacific) and a rolling restart at 1PM SLT.
