Mar <var data-var='date'>22</var>, <var data-var='time'>10:02</var> UTC Resolved - On March 22, 2026, between 09:05 UTC and 10:02 UTC, users may have experienced intermittent errors and increased latency when performing Git http read operations. On average, the error rate was 3.84% and peaked at 15.55% of requests to the service. The issue was caused by elevated latency in an internal authentication service within one of our regional clusters. We mitigated the issue by redirecting traffic away from the affected cluster at 09:39 UTC, after which error rates returned to normal. The incident was fully resolved at 10:02 UTC. We are working to scale the authentication service and reduce our time to detection and mitigation of issues like this one in the future.Mar <var data-var='date'>22</var>, <var data-var='time'>09:27</var> UTC Update - We are investigating intermittently high latency and errors from Git operations.Mar <var data-var='date'>22</var>, <var data-var='time'>09:08</var> UTC Investigating - We are investigating reports of impacted performance for some GitHub services.

During the first incident, the average error rate was ~53% and peaked at ~93% of requests to the service. During the second incident, the average error rate was ~99%% and peaked at ~100%% of requests with significant retry amplification. Both incidents were caused by the same underlying system authentication issue that prevented the service from connecting to its backing datastore. We mitigated each incident by rotating the affected credentials, which restored connectivity and returned error rates to normal. The mitigation time was 01:24. The second occurrence was due to an incomplete remediation of the first.

During this time, average delivery latency increased from a baseline of approximately 5 seconds to a peak of approximately 160 seconds. This was due to resource constraints in the webhook delivery pipeline, which caused queue backlog growth and increased delivery latency. We mitigated the incident by shifting traffic and adding capacity, after which webhook delivery latency returned to normal.

Errors starting and connecting to Codespaces

Mar <var data-var='date'>13</var>, <var data-var='time'>16:15</var> UTC Resolved - On March 13, 2026, between 13:35 UTC and 16:02 UTC, a configuration change to an internal authorization service reduced its processing capacity below what was needed during peak traffic. This caused intermittent timeouts when other GitHub services checked user permissions, resulting in four to five waves of errors over roughly two hours and forty minutes. In total, 0.4% of users were denied access to actions they were authorized to perform. The root cause was a resource right-sizing change deployed to the authorization service the previous day. It reduced CPU allocation below what was required at peak, causing the service's network gateway to throttle under load. Because the change was deployed after peak traffic on March 12, the reduced capacity wasn't surfaced until the next day's peak. The incident was mitigated by manually scaling up the authorization service and reverting the configuration change. To prevent recurrence, we are adding further resource utilization monitors across our entire stack to detect throttling and improving error handling so transient infrastructure timeouts are distinguished from authorization failures, enabling quicker detection of the root issue.Mar <var data-var='date'>13</var>, <var data-var='time'>16:02</var> UTC Update - We have deployed mitigations and are actively monitoring for recovery.

Degraded Codespaces experience

Mar <var data-var='date'>12</var>, <var data-var='time'>06:02</var> UTC Resolved - On March 12, 2026 between 02:30 and 06:02 UTC some GitHub Apps were unable to mint server to server tokens, resulting in 401 Unauthorized errors. During the outage window, ~1.3% of requests resulted in 401 errors incorrectly. This manifested in GitHub Actions jobs failing to download tarballs, as well as failing to mint fine-grained tokens. During this period, approximately 5% of Actions jobs were impacted The root cause was a failure with the authentication service’s token cache layer, a newly created secondary cache layer backed by Redis – caused by Kubernetes control plane instability, leading to an inability to read certain tokens which resulted in 401 errors. The mitigation was to fallback reads to the primary cache layer backed by mysql. As permanent mitigations, we have made changes to how we deploy redis to not rely on the Kubernetes control plane and maintain service availability during similar failure modes. We also improved alerting to reduce overall impact time from similar failures.

Degraded experience with Copilot Code Review

Mar <var data-var='date'>11</var>, <var data-var='time'>15:02</var> UTC Resolved - On March 11, 2026, between 14:25 UTC and 14:34 UTC, the REST API platform was degraded, resulting in increased error rates and request timeouts. REST API 5xx error rates peaked at ~5% during the incident window with two distinct spikes: the first impacting REST services broadly, and the second driven by sustained timeouts on a subset of endpoints. The incident was caused by a performance degradation in our data layer, which resulted in increased query latency across dependent services. Most services recovered quickly after the initial spike, but resource contention caused sustained 5xx errors due to how certain endpoints responded to the degraded state. A fix addressing the behavior that prolonged impact has already been shipped. We are continuing to work to resolve the primary contributing factor of the degradation and to implement safeguards against issues causing cascading impact in the future.Mar <var data-var='date'>11</var>, <var data-var='time'>15:02</var> UTC Update - We are investigating elevated timeouts that affected GitHub API requests.

Mar <var data-var='date'>10</var>, <var data-var='time'>23:00</var> UTC Resolved - On March 10, 2026, between 23:00 UTC and 23:40 UTC, the Webhooks service was degraded and ~6% of users experienced intermittent errors when accessing webhook delivery history, retrying webhook deliveries, and listing webhooks via the UI and API. Approximately 0.37% of requests resulted in errors, while at peak 0.5% of requests resulted in errors. This was due to unhealthy infrastructure. We mitigated the incident by redeploying affected services, after which service health returned to normal. We are working to improve detection of unhealthy infrastructure and strengthen service safeguards to reduce time to detect and mitigate similar issues in the future.

Incident With Webhooks

Mar <var data-var='date'> 9</var>, <var data-var='time'>17:03</var> UTC Resolved - On March 9, 2026, between 15:03 and 20:52 UTC, the Webhooks API experienced was degraded, resulted in higher average latency on requests and in certain cases error responses. Approximately 0.6% of total requests exceeded the normal latency threshold of 3s, while 0.4% of requests resulted in 500 errors. At peak, 2.0% experienced latency greater than 3 seconds and 2.8% of requests returned 500 errors. The issue was caused by a noisy actor that led to resource contention on the Webhooks API service. We mitigated the issue initially by increasing CPU resources for the Webhooks API service, and ultimately applied lower rate limiting thresholds to the noisy actor to prevent further impact to other users. We are working to improve monitoring to more quickly ascertain noisy traffic and will continue to improve our rate-limiting mechanisms to help prevent similar issues in the future.Mar <var data-var='date'> 9</var>, <var data-var='time'>17:03</var> UTC Update - Webhooks is operating normally.Mar <var data-var='date'> 9</var>, <var data-var='time'>15:56</var> UTC Update - We are experiencing latency on the API and UI endpoints.

Codespaces in other regions were not affected. The create and resume failures were caused by degraded network connectivity between our control plane services and the VMs hosting the codespaces. This was resolved by redirecting traffic to an alternate site within the region. While we are addressing the core network infrastructure issue, we have also improved our observability of components in this area to improve detection. This will also enable our existing automated failovers to cover this failure mode. These changes will prevent or significantly reduce the time any similar incident causes user impact.Mar <var data-var='date'> 9</var>, <var data-var='time'>03:51</var> UTC Update - This incident has been resolved.

Actions is experiencing degraded availability

Mar <var data-var='date'> 5</var>, <var data-var='time'>19:30</var> UTC Resolved - On Mar 5, 2026, between 16:24 UTC and 19:30 UTC, Actions was degraded. During this time, 95% of workflow runs failed to start within 5 minutes with an average delay of 30 minutes and 10% workflow runs failed with an infrastructure error. This was due to Redis infrastructure updates that were being rolled out to production to improve our resiliency. These changes introduced a set of incorrect configuration change into our Redis load balancer causing internal traffic to be routed to an incorrect host leading to two incidents. We mitigated this incident by correcting the misconfigured load balancer. Actions jobs were running successfully starting at 17:24 UTC. The remaining time until we closed the incident was burning through the queue of jobs. We immediately rolled back the updates that were a contributing factor and have frozen all changes in this area until we have completed follow-up work from this. We are working to improve our automation to ensure incorrect configuration changes are not able to propagate through our infrastructure. We are also working on improved alerting to catch misconfigured load balancers before it becomes an incident. Additionally, we are updating the Redis client configuration in Actions to improve resiliency to brief cache interruptions.Mar <var data-var='date'> 5</var>, <var data-var='time'>19:17</var> UTC Update - Webhooks is operating normally.Mar <var data-var='date'> 5</var>, <var data-var='time'>19:05</var> UTC Update - Actions is operating normally.Mar <var data-var='date'> 5</var>, <var data-var='time'>18:59</var> UTC Update - Actions is now fully recovered.Mar <var data-var='date'> 5</var>, <var data-var='time'>18:15</var> UTC Update - The queue of requested Actions jobs continues to make progress. Job delays are now approximately 6 minutes and continuing to decrease.Mar <var data-var='date'> 5</var>, <var data-var='time'>17:48</var> UTC Update - We are back to queueing Actions workflow runs at nominal rates and we are monitoring the clearing of queued runs during the incident.Mar <var data-var='date'> 5</var>, <var data-var='time'>17:25</var> UTC Update - We have applied mitigations for connection failures across backend resources and we are observing a recovery in queueing Actions workflow runs.Mar <var data-var='date'> 5</var>, <var data-var='time'>16:52</var> UTC Update - We are observing delays in queuing Actions workflow runs.

Multiple services are affected, service degradation

Mar <var data-var='date'> 5</var>, <var data-var='time'>01:30</var> UTC Resolved - On March 5, 2026, between 12:53 UTC and 13:35 UTC, the Copilot mission control service was degraded. This resulted in empty responses returned for users' agent session lists across GitHub web surfaces. Impacted users were unable to see their lists of current and previous agent sessions in GitHub web surfaces. This was caused by an incorrect database query that falsely excluded records that have an absent field. We mitigated the incident by rolling back the database query change. There were no data alterations nor deletions during the incident. To prevent similar issues in the future, we're improving our monitoring depth to more easily detect degradation before changes are fully rolled out.Mar <var data-var='date'> 5</var>, <var data-var='time'>01:30</var> UTC Update - Copilot coding agent mission control is fully restored. Tasks are now listed as expected.Mar <var data-var='date'> 5</var>, <var data-var='time'>01:21</var> UTC Update - Users were temporarily unable to see tasks listed in mission control surfaces. The ability to submit new tasks, view existing tasks via direct link, or manage tasks was unaffected throughout. A revert is currently being deployed and we are seeing recovery.Mar <var data-var='date'> 5</var>, <var data-var='time'>01:13</var> UTC Investigating - We are investigating reports of impacted performance for some GitHub services.

Mar <var data-var='date'> 5</var>, <var data-var='time'>01:13</var> UTC Resolved - On March 5th, 2026, between approximately 00:26 and 00:44 UTC, the Copilot service experienced a degradation of the GPT 3.5 Codex model due to an issue with our upstream provider. Users encountered elevated error rates when using GPT 3.5 Codex, impacting approximately 30% of requests. No other models were impacted. The issue was resolved by a mitigation put in place by our provider.Mar <var data-var='date'> 5</var>, <var data-var='time'>01:13</var> UTC Update - The issues with our upstream model provider have been resolved, and gpt-5.3-codex is once again available in Copilot Chat and across IDE integrations. We will continue monitoring to ensure stability, but mitigation is complete.Mar <var data-var='date'> 5</var>, <var data-var='time'>00:53</var> UTC Update - We are experiencing degraded availability for the gpt-5.3-codex 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.

Some OpenAI models degraded in Copilot

Mar <var data-var='date'> 3</var>, <var data-var='time'>21:11</var> UTC Resolved - On March 3, 2026, between 19:44 UTC and 21:05 UTC, some GitHub Copilot users reported that the Claude Opus 4.6 Fast model was no longer available in their IDE model selection. After investigation, we confirmed that this was caused by enterprise administrators adjusting their organization's model policies, which correctly removed the model for users in those organizations. No users outside the affected organizations lost access. We confirmed that the Copilot settings were functioning as designed, and all expected users retained access to the model. The incident was resolved once we verified that the change was intentional and no platform regression had occurred.Mar <var data-var='date'> 3</var>, <var data-var='time'>21:05</var> UTC Update - We believe that all expected users still have access to Claude Opus 4.6. We confirm that no users have lost access.Mar <var data-var='date'> 3</var>, <var data-var='time'>20:31</var> UTC Investigating - We are investigating reports of degraded performance for Copilot
