At 1:26am SLT (US Pacific), with a concurrent population of 24,831 inworld search and asset systems began to fail, rapidly becoming non-responsive. There area also reports about teleport failures, and Linden Dollar balances not loading, the map not working, and the inability to add or remove attachments.

As a bonus, the Second Life Support Portal doesn't seem to be working (reporting 'invalid querystring') either. There is, as yet, no word from Linden lab about the issues.

[UPDATE]

At 2:16AM, Linden Lab acknowledged the problem, indicating that the Second Life website was giving troubles from approximately 15 minutes before the inworld issues began.

While the grid and the website have apparently both recovered, Linden Lab says they are investigating the cause.

[3:00AM] The grid continues to behave in a less than stable fashion. Linden Lab says the inworld search system is going to be taken offline while the investigation continues.

[4:00AM] Linden Lab reports that everything is back to normal - reports from users seem to indicate the same thing.
