More information would be helpful to clients; I'm getting emails from clients this weekend and they are concerned about if these errors are attributed to their version of AC, and what we can do to fix the problem.
Updox has their status page; any time we plan maintenance on production systems, we schedule it around practice hours, communicate it, and test it after we bring the system back up. AC may have the same level of operational methodology, but by not communicating, users become concerned.
