I tried to log on just now, and couldn't. Sure enough, the status report page showed that database maintenance is underway. People who want Second Life to be like it was in the "good old days" now have their wish in a way, though not of course what they'd say they meant if you asked them.
I can't remember the last time I wasn't able to log on--at least the last time that I can say for sure was due to issues with the centralized part of Second Life. I would say that indicates that those responsible for the reliability of that part of SL are doing a good job. Thank you!
Carly Simon got it right way back when. These are the good old days.
UPDATE: Even this morning, it's not like the good old days; downtime was just half an hour.
