Most projects have been brought back up, and the team is working on the remaining projects, which should be completed soon.
This issue was related to specific underlying hardware in the region, so this was isolated to only projects on that hardware. Project lifecycle operations (restarts, upgrades, etc) broadly across the region remain available.
All projects affected by the upstream infrastructure issues, and mitigation efforts are underway internally. These affected projects will be brought back up on new hardware as quickly as possible.
