We are still implementing an overall fleet-wide mitigation. In the meantime, we are working with our support team to apply case-by-case mitigations to unblock customers. These interim solutions may restore service but are not permanent fixes and may have some operational constraints. The next update will happen at 12pm UTC

We've seen capacity improve in germanywestcentral and have applied mitigations for eastus2. We're still actively working on the a fleet-wide mitigation and expect to deploy today

We've implemented a code mitigation and are testing the change before deploying to production

We have deployed the mitigation for M30+ instance sizes, however M10 and M20 may still experience capacity constraints. We recommend customers upgrade to M30+ if they are continuing to experience issues.
