All services are currently up, however we are aware that a few customers received errors when visiting their FogBugz On Demand accounts earlier this evening. This problem has been traced to a deployment script that helps us manage new software releases for FogBugz On Demand. Generally speaking, we will be both increasing the verbosity in our deployment tools and making our post-deployment tests more robust.
We apologize for the service interruption, and ask that you contact us by emailing customer-service@fogcreek.com is you have any questions.
