It's time for the first FogBugz upgrade of the new year. On Monday, we will be upgrading all FogBugz On Demand accounts to version 8.15.169. We will be gradually upgrading account starting at 10am EST (UTC-5) and finishing by 5pm EST. You shouldn't see any downtime during this window. We will also be running a per-account schema change at each account's local midnight. Again, this shouldn't result in significant downtime. Finally, we will be upgrading the main fbhosted schema from 10pm to 11pm est on Monday. There may be up to 5 minutes of downtime during that window.
