We are investigating reports of degraded performance for Copilot AI Model Providers
20:14 Official
Investigating
We are experiencing degraded availability for gpt-5.6-sol-fast, gpt-5.6-sol, gpt-6.1-terra, and gpt-6-luna in Copilot products and IDE surfaces. This is due to an issue with an upstream model provider. While we work with them to resolve the issue, we recommend choosing another model or selecting 'Auto' to continue using Copilot.

Investigating
We are in contact with the upstream provider and monitoring as they work towards resolution. For customers who are impacted we recommend choosing another model or selecting ‘Auto’ to continue using Copilot.

Between 19:05 and 21:27 UTC on November 13, 2026, GitHub Copilot experienced degradation affecting GPT-6.1 Terra, GPT-5.6 Sol, and GPT-6 Luna models. Users encountered elevated error rates when using these models. The degradation was caused by an issue with an upstream model provider. GitHub engineers detected the issue through automated monitoring and coordinated with the provider. Our automated model-warning system activated in-product warnings for affected models during the incident. Service returned to normal after the provider implemented a mitigation.

What our checkpoints saw

HostTracker's checkpoints, which test github.com from several locations, recorded no outage of 5 minutes or longer during this incident. A provider can report a problem that affects only some features, regions or accounts, which a check of the main address does not see. The live GitHub status shows what our checks see right now.

Does your product depend on GitHub?

An outage like this one reaches your users through your product, and most teams hear about it from a customer rather than from a dashboard. HostTracker watches any endpoint you name - your own site, an API you call, a vendor you resell - from 300+ locations, confirms a failure from several of them before it says anything, and then tells you by email, SMS, voice call or your chat tool.

You get the same record you are reading here for your own services: every outage timestamped, with the checks that observed it.
