You might have noticed the site was down for a few days about a week ago. We had some drive failures that ravaged the 4-disk hardware-RAID5 data storage scheme on the server. So short story: we didn’t have time to recover because of BTS traffic and the cost of being down, so it was reformatted. I lost data posted since May, but that was all recovered from RSS feed backups. It should be stable now.
On another note: you no longer need to register to leave comments, and gravatars are now turned on. I’m also generating and downloading backups daily now. :)
