We've encountered some memory usage problems with the latest version of FogBugz On Demand that didn't show up in our staging environment.
To prevent this from causing any problems, we're going to downgrade all accounts to the previous version. This process causes no downtime. However, any features and fixes released will be unavailable until we can fix the issue and re-deploy the new version.
We will be doing the rollback as soon as all preparation is completed, and should be completed in the next two hours.
If you have any questions or concerns, please don't hesitate to reach out to us!
