RESOLVED 12 days ago - at 10/23/2025 10:59AM

Between 10:12 and 10:18 UTC a change to the way back-end resources are allocated led to a scenario whereby the services processing requests began being forcibly restarted.

This was caused by the services rapidly exceeding predefined resource limits and being taken out of service.

This resulted in a partial outage that affected a small number of requests.

Our internal monitoring alerted us to the issue and the changes were reverted.

We're continuing to monitor the situation but consider this incident resolved.

Full service was restored at 10:18 UTC.
