There are lingering issues with about 5% of the servers that make up Second Life, which translates to about 800 regions being offline. We are working to get those servers back online so that all enabled regions can be running again.
We’ll post updates as more news is available.
[Update: 10:40am] The problem has been corrected, and the regions are restarting. Only about 200 regions remain offline at this point.[Update: 11:08am] Looks like we’re back in charted waters, with all regions accounted for. Smooth sailing ahead!
