Incident with Packages

Resolved - On August 14, 2025, between 17:50 UTC and 18:08 UTC, the Packages NPM Registry service was degraded. During this period, NPM package uploads were unavailable and approximately 50% of download requests failed. We identified the root cause as a sudden spike in Packages publishing activity that exceeded our service capacity limits. We are implementing better guardrails to protect the service against unexpected traffic surges and improving our incident response runbooks to ensure faster mitigation of similar issues.
Aug 14, 18:37 UTC

Update - The NPM registry has now returned to normal functioning.
Aug 14, 18:37 UTC

Update - The NPM registry service is currently experiencing intermittent availability issues. Other package registries should be unaffected. Investigations are ongoing.

Incident with Actions

Resolved - On August 14, 2025, between 02:30 UTC and 06:14 UTC, GitHub Actions was degraded. On average, 3% of workflow runs were delayed by at least 5 minutes. The incident was caused by an outage in a downstream dependency that led to failures in backend service connectivity in one region. At 03:59 UTC, we evacuated a majority of services in the impacted region, but some users may have seen ongoing impact until all services were fully evacuated at 06:14 UTC. We are working to improve monitoring and processes of failover to reduce our time to detection and mitigation of issues like this one in the future.

Incident with search on GitHub we are seeing increased failure rates

Resolved - On August 12, 2025, between 13:30 UTC and 17:14 UTC, GitHub search was in a degraded state. Users experienced inaccurate or incomplete results, failures to load certain pages (like Issues, Pull Requests, Projects, and Deployments), and broken components like Actions workflow and label filters.

Most user impact occurred between 14:00 UTC and 15:30 UTC, when up to 75% of search queries failed, and updates to search results were delayed by up to 100 minutes.

The incident was triggered by intermittent connectivity issues between our load balancers and search hosts. While retry logic initially masked these problems, retry queues eventually overwhelmed the load balancers, causing failure. The query failures were mitigated at 15:30 UTC after throttling our search indexing pipeline to reduce load and stabilize retries. The connectivity failures were resolved at 17:14 UTC after the automated reboot of a search host, causing the rest of the system to recover.

We have improved internal monitors and playbooks, and tuned our search cluster load balancer to further mitigate the recurrence of this failure mode. We continue to invest in resolving the underlying connectivity issues.
Aug 12, 17:56 UTC

Update - Service availability has been mostly restored, but some users will continue to see increased request latency and stale search results. We are still working towards full recovery.
Aug 12, 17:07 UTC

Update - Service availability has been mostly restored, but increased load/query latency and stale search results persist. We continue to work towards full mitigation.
Aug 12, 16:33 UTC

Update - We are seeing partial recovery in service availability, but still see inconsistent experiences and stale search data across services. Investigation and mitigations are underway.
Aug 12, 15:48 UTC

Update - We are experiencing increased latency in our API layers and inconsistently degraded experiences when loading or querying issues, pull requests, labels, packages, releases, workflow runs, projects, and repositories, among others. Investigation is underway.
Aug 12, 15:20 UTC

Update - We are investigating reports of degraded performance in services backed by search. The team continues to investigate why requests are failing to reach our search clusters.
Aug 12, 14:53 UTC

Update - Packages is experiencing degraded performance. We are continuing to investigate.
Aug 12, 14:30 UTC

Investigating - We are investigating reports of degraded performance for API Requests, Actions, Issues and Pull Requests

Disruption with some GitHub services

Resolved - On August 11, 2025, from 18:41 to 18:57 UTC, GitHub customers experienced errors and increased latency when loading GitHub’s web interface. During this time, a configuration change to improve our UI deployment system caused a surge in requests to a backend datastore. This change led to an unexpected spike in connection attempts to our datastore and saturated its connection backlog and resulted in intermittent failures to serve required UI content. This resulted in elevated error rates for frontend requests.

The incident was mitigated by reverting the configuration, which restored normal service.

Following mitigation, we are evaluating improvements to our alerting thresholds and exploring architectural changes to reduce load to this datastore and improve the resilience of our UI delivery pipeline.
Aug 11, 18:57 UTC

Update - Logged out users may see intermittent errors when loading github.com webpages. Investigation is ongoing.

Incident with Pull Requests

Resolved - At 15:33 UTC on August 5, 2025, we initiated a production database migration to drop a column from a table backing pull request functionality. While the column was no longer in direct use, our ORM continued to reference the dropped column in a subset of pull request queries. As a result, there were elevated error rates across pushes, webhooks, notifications, and pull requests with impact peaking at approximately 4% of all web and REST API traffic.

We mitigated the issue by deploying a change that instructed the ORM to ignore the removed column. Most affected services recovered by 16:13 UTC. However, that fix was applied only to our largest production environment. An update to some of our custom and canary environments did not pick up the fix and this triggered a secondary incident affecting ~0.1% of pull request traffic, which was fully resolved by 19:45 UTC.

While migrations have protections such as progressive roll-out first targeting validation environments and acknowledge gates, this incident identified an application monitoring gap that would have prevented continued rollout when impact was observed. We will add additional automation and safeguards to prevent future incidents without requiring human intervention. We are also already working on a way to streamline some types of changes across environments, which would have prevented the second incident from occurring.
