Due to a storage issue on Microsoft Azure a few Aspex Azure servers experienced degraded performance for a time this morning. The issue has been resolved and all servers are performing normally.
Storage - West Europe - Mitigated
Summary of Impact: Between 23:20 UTC on 21 Oct 2019 and 04:32 UTC on 22 Oct 2019, a subset of customers using Storage in West Europe may have experienced difficulties connecting to resources hosted in this region. Preliminary Root Cause: Engineers determined that an inconsistency within an internal system state caused a single storage scale unit in West Europe to enter an unhealthy state which resulted in downstream availability impact to several services in the region. Mitigation: Engineers developed, tested, and deployed a platform hotfix to correct the inconsistency, restoring dependent services and mitigating the issue. Next Steps: Engineers will continue to investigate to establish the full root cause and prevent future occurrences, and the full Root Cause Analysis will be made available within 72 hours.
