On August 10th, 2026, from 20:31 to 22:19 UTC, users in the South America / São Paulo region experienced errors when signing in to ODC. This prevented affected users from accessing their Production applications and also affected the ODC Portal and ODC Studio.

The issue was detected through customer reports and monitoring. Our investigation found that a fault in an internal caching component of our identity service was preventing it from issuing sign-in tokens, even though the service otherwise appeared to be running normally.

To restore service, our team restarted the affected identity service, which cleared the fault and allowed token issuance to resume. We confirmed with affected customers that sign-in and application access had returned to normal before closing the incident.

We have identified additional monitoring and preventive improvements for this component and are prioritising their rollout to help reduce the risk of similar issues recurring. We apologise for any disruption caused and thank you for your patience.
