## Summary

GitHub reported a series of outages and degraded performance across **Actions, Pages, Webhooks, Copilot models, Dependabot alerts, and Projects** in October 2026. The most severe incident on **October 19** caused **5.13% of GitHub-hosted runner jobs to delay starting**, **8.47% of Actions API requests to fail**, and **workflow status updates, logs, and Pages deployments to stall**. The root cause was a **network link overload** in a data center after an internal Actions service flooded cache servers with retries, disrupting shared infrastructure. GitHub mitigated the issue by isolating the service and reducing network load, then processed delayed work. Other incidents included **model provider failures** affecting Copilot’s **GPT-5.3-Codex, GPT-6.1 Sol, and MAI Code 1.1 Flash**, **Dependabot alert backlogs** delaying vulnerability fixes, and **storage throttling** in Actions workflows, which caused **up to 7-minute delays** in job updates. GitHub attributed some failures to **scheduled migrations** and **cleanup jobs** on installation records, leading to **59 million deleted records** and replication delays. The company is updating processes to prevent recurrence, including **disabling overlapping cleanup jobs** and **blocking read cutovers during high replication delays**. A full root cause analysis has not yet been released for most incidents.

## Key points

- October 19 outage delayed **5.13% of GitHub-hosted runner jobs** and caused **8.47% of Actions API requests to fail** due to network overload
- Copilot models like **GPT-5.3-Codex and MAI Code 1.1 Flash** faced degraded availability from **upstream provider issues** in mid-October
- Dependabot alerts saw **processing backlogs** lasting days, with delays up to **70+ minutes** for audit log events

## Why it matters

These outages highlight GitHub’s reliance on third-party model providers and internal infrastructure bottlenecks, risking developer workflows. The **Actions network overload** and **Dependabot delays** underscore scaling challenges as usage grows, while Copilot’s model failures show fragility in AI-powered tooling. Developers and businesses using GitHub for CI/CD, hosting, or AI assistance may face intermittent disruptions until fixes are fully implemented.
