Second Life grid logins closed

For those of you who have been in-world since Midnight SLT (US Pacific) it is probably no surprise to you that the Second Life grid has been behaving erratically for the last 11 hours.

This has been pinned on unstable database performance and Linden Lab has closed logins for an unspecified amount of time to take control of things. If it is related to recent database issues then we can expect 30-45 minutes of closure before the Lab gets on top of the database problems.
