This morning, just before 7 am SLT, when I tried to login into Second Life, I got an error message:
Login failed.
Second Life is closed for emergency maintenance. Please check the www.secondlife.com/status web page for updates. Thank you for your patience.
The web site told us that there are severe problems with the upstream internet server provider. Lots of packets lost.
I kept checking every five minutes, but even at 8 am SLT, the problem had not been resolved.
