On 2024-01-21 at 3:38 UTC, we experienced an incident that affected customers using Codespaces. Customers encountered issues creating and resuming Codespaces in multiple regions due to operational issues with compute and storage resources.
Around 25% of customers were impacted, primarily in East US and West Europe. We re-routed traffic for Codespace creations to less impacted regions, but existing Codespaces in these regions may have been unable to resume during the incident.
By 7:30 UTC, we had recovered connectivity to all regions except West Europe, which had an extended recovery time due to increased load in that particular region. The incident was resolved on 2024-01-21 at 9:34 UTC once Codespace creations and resumes were working normally in all regions.
