On March 8, 2025, between 17:16 UTC and 18:02 UTC, GitHub Actions and Pages services experienced degraded performance leading to delays in workflow runs and Pages deployments. During this time, 34% of Actions workflow runs experienced delays, and a small percentage of runs using GitHub-hosted runners failed to start. Additionally, Pages deployments for sites without a custom Actions workflow (93% of them) did not run, preventing new changes from being deployed.
An unexpected data shape led to crashes in some of our pods. We mitigated the incident by excluding the affected pods and correcting the data that led to the crashes. We’ve fixed the source of the unexpected data shape and have improved the overall resilience of our service against such occurrences.

On March 7, 2025, from 09:30 UTC to 11:07 UTC, we experienced a networking event that disrupted connectivity to our search infrastructure, impacting about 25% of search queries and indexing attempts. Searches for PRs, Issues, Actions workflow runs, Packages, Releases, and other products were impacted, resulting in failed requests or stale data. The connectivity issue self-resolved after 90 minutes. The backlog of indexing jobs was fully processed and saw recovery soon after, and queries to all indexes also saw an immediate return to normal throughput.
We are working with our cloud provider to identify the root cause and are researching additional layers of redundancy to reduce customer impact in the future for issues like this one. We are also exploring mitigation strategies for faster resolution.

On March 3rd 2025 between 04:07 UTC and 09:36 UTC various GitHub services were degraded with an average error rate of 0.03% and peak error rate of 9%. This issue impacted web requests, API requests, and git operations.
This incident was triggered because a network node in one of GitHub's datacenter sites partially failed, resulting in silent packet drops for traffic served by that site. At 09:22 UTC, we identified the failing network node, and at 09:36 UTC we addressed the issue by removing the faulty network node from production.
In response to this incident, we are improving our monitoring capabilities to identify and respond to similar silent errors more effectively in the future.

Codespaces will be undergoing maintenance in Europe and Southeast Asia from 17:00 UTC Friday February 28 to 02:00 UTC Saturday March 1. Maintenance will begin in North Europe at 17:00 UTC Friday February 28, followed by Southeast Asia, concluding in UK South. Each region will take 2-3 hours to complete.
During this time period, users may experience connectivity issues with new and existing Codespaces.
Please ensure that any uncommitted changes that you may need during the maintenance window are committed and pushed. Codespaces with any uncommitted changes will be accessible as usual once maintenance is complete.
Thank you for your patience as we work to improve our systems.

On February 28th, 2025, between 05:49 UTC and 06:55 UTC, a newly deployed background job caused increased load on GitHub’s primary database hosts, resulting in connection pool exhaustion. This led to degraded performance, manifesting as increased latency for write operations and elevated request timeout rates across multiple services.
The incident was mitigated by halting execution of the problematic background job and disabling the feature flag controlling the job execution. To prevent similar incidents in the future, we are collaborating on a plan to improve our production signals to better detect and respond to query performance issues.

On February 27, 2025, between 11:30 UTC and 12:22 UTC, Actions experienced degraded performance, leading to delays in workflow runs. On average, 5% of Actions workflow runs were delayed by 31 minutes. The delays were caused by updates in a dependent service that led to failures in Redis connectivity in one region. We mitigated the incident by failing over the impacted service and re-routing the service’s traffic out of that region. 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.
