The site is now back up after many long hours and is working perfectly. The delay was due to the RAID array on the main server - not only was a drive not working, but the configuration was wacky and needed to be fixed. This led to needing 2 separate array rebuilds.
Thanks to everyone for your patience during the maintenance - and if you're glad to see the site back up, please stop by the profiles of holms and dmitrijus
and drop them a thanks. They spent all day today, again, helping out with making sure the servers are working during the maintenance, and I couldn't have done it without them.
And if you want to help AP continue running, as unfortunately now we'll be spending a few more hundred dollars a month on server support, here's the link to donate to the cause - anything is appreciated!
I'm off to a much, much needed dinner and adult beverage
