A scheduled activity to shift the back-end API DNS configuration between DNS providers occurred on September 3rd at approximately 14:00 UTC. The impact began soon after at 14:06 UTC. Following the DNS update, the Block Storage team observed a loss of connectivity between internal services. As a result, customers attempting to create, modify, or delete block storage volumes found their operations stalled in the “creating”, “resizing”, or “deleting” states. This issue was mitigated at approximately 16:32 when the backlog of API requests was processed after rolling back the configuration update applied during this scheduled activity.
