From January 5, 2026, 00:00 UTC to January 10, 2026, 02:30 UTC, customers using the AI Controls public preview feature experienced delays in viewing Copilot agent session data. Newly created sessions took progressively longer to appear, initially hours, then eventually exceeding 24 hours. Since the page displays only the most recent 24 hours of activity, once processing delays exceeded this threshold, no recent data was visible. Session data remained available in audit logs throughout the incident.
Inefficient database queries in the data processing pipeline caused significant processing latency, creating a multi-day backlog. As the backlog grew, the delay between when sessions occurred and when they appeared on the page increased, eventually exceeding the 24-hour display window.
The issue was resolved on January 10, 2026, 02:30 UTC, after query optimizations and a database index were deployed. We are implementing enhanced monitoring and automated testing to detect inefficient queries before deployment to prevent recurrence.

Update -
Our queue has cleared. The last 24 hours of agent session history should now be visible on the AI Controls UI. No data was lost due to this incident.

Update -
We estimate the backlogged queue will take 3 hours to process. We will post another update once it is completed, or if anything changes with the recovery process.

Update -
We have deployed an additional fix and are beginning to see recovery to the queue preventing AI Sessions from showing in the AI Controls UI. We are working on an estimate for when the queue will be fully processed, and will post another update once we have that information.

Jan 9, 23:44 UTC
Update -
We are seeing delays processing the AI Session event queue, which is causing sessions to not be displayed on the AI Controls UI. We have deployed a fix to improve the queue processing and are monitoring for effectiveness. We continue to investigate other mitigation paths.

Resolved -
On January 6th, 2026, between approximately 8:41 and 10:07 UTC, the Copilot service experienced a degradation of the GPT-5.1-Codex-Max model due to an issue with our upstream provider. During this time, up to 14.17% of requests to GPT-5.1-Codex-Max failed. No other models were impacted.
The issue was resolved by a mitigation put in place by our provider. GitHub is working with our provider to further improve the resiliency of the service to prevent similar incidents in the future.

Update -
We are experiencing degraded availability for the GPT-5.1-Codex-Max model in Copilot Chat, VS Code and other Copilot products. This is due to an issue with an upstream model provider. We are working with them to resolve the issue.
Other models are available and working as expected.
