Guys:
We had difficulty with what we'd hoped would be a routine drive swap today and had to fail over, for a few hours, to a secondary web server. After a little work, we were able to resuscitate our primary server, rebuild its array with the new drive, and return to production on it.
That's great news for us--the site is back to full strength, full capacity, and full primary/secondary redundancy--but it means all posts and comments from about 12:30PM to 4:00PM today, when the site was running on the secondary box, have been lost. Given the way things went down, some loss of messages for a time period was inevitable. Apologies, though, for the inconvenience.
