We're re-enabled access to mail that was delivered before our array failure on Thursday. Users should be able to read and manage their old mail. Unfortunately, you'll need to login to one of our shell servers to read your mail; we haven't brought POP or IMAP back up yet. At the same time, we're working on delivering mail that was queued during the downtime. Please have patience; we're working very hard on it.
Also, we're aware of the issues with databases and are trying to debug the problem.
I'm currently attempting to probe our disk image of the array to see if I can find any files that were lost during the restoration process. Since the image is about ~1 TB, it's not going as quickly as I'd like, but it's still running.
