Update
We have confirmed the original mitigation to failover has resolved the issue causing Codespaces to become unavailable. We are evaluating if there is a path to recover unpushed data from the approximately 2000 Codespaces that are currently in the shutting down state. We will be resolving this incident and will detail the next steps in our public summary.

Update
For Codespaces that were stuck in the shutting down state and have been resumed, we've identified an issue that is causing the contents Codespace to be irrecoverably lost which has impacted approximately 250 Codespaces. We are actively working on a mitigation to prevent any more Codespaces currently in this state from being forced to shut down to prevent the potential data loss.

Update
We're continuing to see improvement with Codespaces that were stuck in in the shutting down state and we anticipate the remaining should self resolve in about an hour.

Update
Some users with Codespaces in West Europe were unable to connect to Codespaces, we have failed over that region and users should be able to create new Codespaces. If a user has a Codespace in a shutting down state, we are still investigating potential fixes and mitigations.
