On June 30, 2026, between approximately 17:30 UTC and 21:45 UTC, users may have experienced connection timeouts and errors related to the Block Storage service in Singapore Expansion, SP (sg-sin-2).

The issue began when one host in the cluster was taken down for maintenance while another host unexpectedly encountered network issues. A configuration issue also contributed to the impact. These factors led to a degraded state that affected performance and, to a limited extent, data availability. We mitigated the impact to customers at 21:45 UTC on June 30, 2026 by correcting the network, configuration and cluster issues.

We apologize for the impact and appreciate your patience and ongoing support. We are making configuration and operational changes to our systems to help prevent this from happening again, and remain committed to continuous improvement.

This summary provides an overview of our current understanding of the incident, given the information available. Our investigation is ongoing, and any information herein is subject to change.
