Nov <var data-var='date'> 4</var>, <var data-var='time'>17:01</var> UTC Resolved - On November 4, 2026, between 15:49 UTC and 16:48 UTC, and again between 17:20 UTC and 17:55 UTC, GitHub Actions, Pages, Webhooks, Code Scanning, and Copilot coding agent experienced delays. During this time, Actions workflow runs and job status updates were delayed by up to 25 minutes. Pages deployments dropped to about 4% of normal volume, webhook deliveries dropped to about 58% of normal volume, and Code Scanning analyses and Copilot coding agent sessions were delayed. Delayed events were processed after mitigation. This incident was caused by a configuration change to an internal event-routing service that unexpectedly paused delivery of several event streams. The change depended on feature flags that were not set up as intended, which the service did not handle gracefully. We mitigated the first period by rolling back the configuration change at 16:14 UTC. The code change itself was not reverted by the rollback, so a subsequent deployment reintroduced it. We mitigated the second period at 17:40 UTC by rolling back again, then processed queued events and cleared backlogs. We are taking several steps to prevent a repeat. The routing service will keep its existing behavior when a feature toggle is missing, so a misconfigured flag can no longer pause delivery. We are adding a pre-deploy check that each routing flag exists and is registered under the correct owning service, and we are making flag ownership less error-prone to set. We are also improving alerting so we detect paused event delivery sooner. Nov <var data-var='date'> 4</var>, <var data-var='time'>16:49</var> UTC Update - The degradation has been mitigated.

Increased task-related errors for Copilot Mission Control

Nov <var data-var='date'> 3</var>, <var data-var='time'>22:41</var> UTC Resolved - On November 3, 2026, between 15:00 UTC and 22:37 UTC, Git operations over HTTPS on GitHub.com were degraded. Clones, fetches, and pushes over HTTPS were slow, and some failed. For about half of Git HTTPS traffic, median response time rose from under 100 milliseconds to as high as 5 seconds. On average, the error rate was 0.65% and peaked at 1.29% of requests to the service. Git operations over SSH were not affected. This was due to a buildup of excess connections on the hosts that serve Git HTTPS traffic, which saturated their network capacity and caused slow and failed responses for all clients served by those hosts. We mitigated the incident by blocking a client traffic pattern at our load balancers and reloading them, which released the excess connections. The block also prevented some users of one third-party integration from performing Git operations over HTTPS until we removed it on November 4 at 13:26 UTC. We are working to alert on sustained Git HTTPS latency sooner and make load balancer mitigations take effect on existing connections immediately.

Elevated errors on GPT-5.4 Nano

Oct <var data-var='date'>30</var>, <var data-var='time'>23:29</var> UTC Resolved - On October 30, 2026, between 20:15 and 21:56 UTC, an advisory-publication-driven fan-out caused an unexpected saturation of network connections to the Dependabot alerts datastore. During this period we observed a high rate of write failures on this datastore; users saw elevated failure rates when dismissing or resolving Dependabot alerts, as well as failures when linking Dependabot update pull requests to Dependabot security alerts.  We also observed delays in creating and updating security alerts that extended through November 2, 2026. The unexpected fan-out was caused by a missing job queue throttle after the queues for the fan-out work were migrated as part of system maintenance. We have restored the fan-out throttle and further isolated and throttled these processes to guard against further disruptions.

Incident with Dependabot

Oct <var data-var='date'>30</var>, <var data-var='time'>19:23</var> UTC Resolved - On October 30, 2026, from 17:50 to 18:32 UTC, Actions, Pages, and Webhooks experienced degraded performance. Actions workflow processing, Pages deployments, and webhook deliveries were delayed, and code search and live updates returned errors. Some Actions queues took additional time to drain after mitigation, and the incident was resolved at 19:23 UTC. The impact was triggered by maintenance on a cloud network gateway connecting an Actions service in the GitHub data center to Redis clusters in the Central US Azure region. The service's Redis client retried aggressively and redialed those connections. That produced a connection storm that saturated the gateway, with about 90% of connection attempts failing. Other services sharing the same network path were degraded as well. We mitigated the incident by removing the affected resources from rotation, which ended the connection storm and allowed the gateway to recover. We have already reduced the number of connection retries in the impacted service and are further improving retry behavior with jittered backoff, shorter connect timeouts, and retry budgets. We are also working with our infrastructure team to make GitHub more resilient to gateway maintenance.

Disruption with GitHub services

Oct <var data-var='date'>29</var>, <var data-var='time'>12:49</var> UTC Resolved - On October 29, 2026, between 05:50 UTC and 12:40 UTC, Copilot agent sessions on GitHub.com and in VS Code were degraded. Live session updates often failed to load, and on average 2.14% of requests to the agent sessions service failed, with a peak of 8.61%. For about 10 minutes around 09:20 UTC, up to 40% of requests to list or create agent sessions failed. Copilot Chat on GitHub.com showed degraded agent session features during this time. The issue occurred when a large increase in task-list requests from a client experiment overloaded the cache that supports the agent sessions service. We mitigated the impact by increasing cache capacity, reducing nonessential load on the cache, and disabling the client experiment. We are moving rate limiting to separate infrastructure, reducing client polling, and improving our alerting so we can detect and respond to this type of overload faster.

Disruption with Copilot Cloud services

Oct <var data-var='date'>28</var>, <var data-var='time'>15:28</var> UTC Resolved - On October 28, 2026, between 13:52 and 15:24 UTC, Copilot users saw errors when using several GPT-family models and the MAI Code 1.1 Flash model. Affected experiences included Copilot Chat in IDEs and on GitHub.com, the Copilot CLI, Copilot Code Review, the Copilot Coding Agent, Code Scanning Autofix, and Code Quality. About 9.73% of requests to the affected models failed, with a peak of about 36.97% at the start of the incident. The errors happened because a credential that we use to authenticate with an upstream model provider became invalid. We mitigated the incident by replacing the credential and redeploying the service. We are strengthening how we manage credentials for upstream providers to prevent this type of failure, returning retryable errors when an upstream provider rejects a request, and improving our monitoring so that we detect and mitigate this type of problem faster in the future.

Disruption with some Copilot services

Oct <var data-var='date'>27</var>, <var data-var='time'>08:00</var> UTC Resolved - Between 0655 and 0801 UTC on 10/27, customers experienced increased failure rates for API and git requests authenticated with server-to-server tokens for GitHub Apps (excluding Actions tokens). During this window, authenticated git operations mistakenly returned 404 for 1.24% (2.6x) of requests on average and 2.49% (5.3x) at peak. These failures were caused by a scheduled maintenance event where GitHub migrated 7 tables between two MySQL clusters in our IAD and Azure Central US datacenters. One of the affected tables stores installation records for GitHub App server-to-server tokens (excluding Actions). We've successfully completed several of these migrations in recent months without notable customer impact. However, in this case, the migration coincided with a scheduled cleanup job on the installation records table, which deleted approximately 59 million records from 0444-0617 UTC. As a result, the gh-ost tooling used in the migration experienced inter-cluster replication delays (up to 1 hour at peak). At 0655 UTC, we begin transitioning reads of the target tables to the new MySQL cluster, with 100% of reads cutover at 0721 UTC. Customer impact began, but was not detected, throughout the read cutover and persisted until completion of the write cutover at 0801 UTC. We are updating our processes and automation to prevent a repeat of this incident, including disabling overlapping cleanup jobs prior to these migrations and blocking the cutover of reads when replication delays are high.

Grok 4.6 and Grok 4.7 Service Issues

Oct <var data-var='date'>23</var>, <var data-var='time'>18:51</var> UTC Resolved - We identified that an advisory-publication driven fan-out was overwhelming Dependabot alert processing on repositories by saturating the queue with its own events, delaying processing of events related to repository pushes. We have now isolated this fan-out and applied a throttle so it runs at a fixed rate and cannot delay other events. This remediation has successfully prevented a new fan-out process impacting users.

Disruption with Dependabot Alerts

Oct <var data-var='date'>23</var>, <var data-var='time'>08:05</var> UTC Resolved - On October 23, 2026, between 07:06 UTC and 07:27 UTC, GitHub Actions workflow run results were delayed. Job status, check run updates, and logs in the GitHub UI and API updated with an average delay of about 2 minutes, and some updates were delayed by up to about 7 minutes. During this window, a storage dependency that Actions uses to process workflow logs and artifacts throttled our requests. This slowed result processing, causing updates to queue up. The queue was fully processed by 07:27 UTC, shortly after the throttling stopped. To reduce the risk of recurrence, we have added several storage accounts to increase capacity, and we are working on additional steps to continue to scale. We are also working with our storage provider to understand why the throttling occurred, and improving how result processing handles storage throttling and how quickly we detect it. Oct <var data-var='date'>23</var>, <var data-var='time'>07:56</var> UTC Update - As of 07:27 UTC, Actions results are delivering within normal SLOs again. Thank you for this patience during this period of delayed Actions results delivery. Our team continues to monitor system health and explore refinements to reduce impact to customers in the future.

Project updates delayed

Oct <var data-var='date'>22</var>, <var data-var='time'>15:18</var> UTC Resolved - On October 22, 2026, from 13:05 to 15:20 UTC, our event streaming platform was degraded resulting in elevated job processing latency spikes of 19-35 seconds and elevated job processing times of 4m – this resulted in delayed Actions workflow and step results (up to 13m), notifications (20m) and repository push events (12m). Recovery for repositories began at 14:32, with Actions recovery beginning at 14:59. The issue reoccurred at 16:26 again impacting Actions runs, repo push events, and notifications. Recovery began at 17:16 and completed at 2:07. The incident was caused by a significant increase in load coupled with client connection storms during a deployment overloading our Kafka event streaming brokers. To prevent future recurrence, we have expanded the affected cluster, shifted traffic to less loaded clusters, and implemented tunable client reconnect backoff.
