Apr 2, 21:48 UTC Resolved - Between 15:20 and 20:18 UTC on Thursday April 2, Copilot Cloud Agent entered a period of reduced performance. Due to an internal feature being developed for Copilot Code Review, the Copilot Cloud Agent infrastructure started to receive an increased number of jobs. This load eventually caused us to hit an internal rate limit, causing all work to suspend for an hour. During this hour, some new jobs would time out, while others would resume once rate limiting ended. ...

Apr 1, 23:45 UTC Resolved - On April 1st, 2026 between 14:40 and 17:00 UTC the GitHub code search service had an outage which resulted in users being unable to perform searches. The issue was initially caused by an upgrade to the code search Kafka cluster ZooKeeper instances which caused a loss of quorum. This resulted in application-level data inconsistencies which required the index to be reset to a point in time before the loss of quorum occurred. Meanwhile, an accidental deploy resulted in...

Apr 1, 16:10 UTC Resolved - On April 1, 2026, between 15:34 UTC and 16:02 UTC, our audit log service lost connectivity to its backing data store due to a failed credential rotation. During this 28-minute window, audit log history was unavailable via both the API and web UI. This resulted in 5xx errors for 4,297 API actors and 127 github.com users. Additionally, events created during this window were delayed by up to 29 minutes in github.com and event streaming. No audit log events were lost; al...

Apr 1, 12:41 UTC Resolved - On April 1, 2026, between 07:29 and 12:41 UTC, some customers experienced elevated 5xx errors and increased latency when using GitHub Copilot features that rely on `/agents/sessions` endpoints (including creating or viewing agent sessions). The issue was caused by resource exhaustion in one of the Copilot backend services handling these requests, in turn, causing timeouts and failed requests. We mitigated the incident by increasing the service’s available compute res...

Mar 31, 21:23 UTC Resolved - On Monday March 31st, 2026, between 13:53 UTC and 21:23 UTC the Pull Requests service experienced elevated latency and failures. On average, the error rate was 0.15% and peaked at 0.28% of requests to the service. This was due to a change in garbage collection (GC) settings for a Go-based internal service that provides access to Git repository data. The changes caused more frequent GC activity and elevated CPU consumption on a subset of storage nodes, increasing late...

Mar 31, 15:10 UTC Resolved - On March 31, 2026, between 06:15 UTC and 15:30 UTC, the GitHub billing usage reports feature was degraded due to reduced server capacity. Customers requesting billing usage reports and loading the top usage by organization and repository on the billing overview and usage pages were impacted. The average error rate for usage report requests was 15%, peaking at 98% over an eight-minute window. For the billing pages, an average of 56% of requests failed to load the top...

Mar 27, 05:00 UTC Resolved - On March 27, 2026, from 02:30 to 04:56 UTC, a misconfiguration in our rate limiting system caused users on Copilot Free, Student, Pro, and Pro+ plans to experience unexpected rate limit errors. The configuration that was incorrectly applied was intended solely for internal staff testing of rate-limiting experiences. Copilot Business and Copilot Enterprise accounts were not affected. During this period, affected users received error messages instructing them to retry ...

Mar 24, 19:51 UTC Resolved - On March 24, 2026, between 15:57 UTC and 19:51 UTC, the Microsoft Teams Integration and Teams Copilot Integration services were degraded and unable to deliver GitHub event notifications to Microsoft Teams. On average, the error rate was 37.4% and peaked at 90.1% of requests to the service -- approximately 19% of all integration installs failed to receive GitHub-to-Teams notifications in this time period. This was due to an outage at one of our upstream dependencies, ...

Mar 22, 10:02 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 err...

Mar 20, 01:58 UTC Resolved - On March 19, 2026, between 01:05 UTC and 02:52 UTC, and again on March 20, 2026, between 00:42 UTC and 01:58 UTC, the Copilot Coding Agent service was degraded and users were unable to start new Copilot Agent sessions or view existing ones. 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 amplifi...
