INCIDENT WITH GITHUB.COM
Summary from the TLDR Dev newsletter
GitHub experienced widespread outages and elevated error rates across multiple services caused by an autoscaling misconfiguration on an Istio sidecar pod that cascaded into load-balancer network saturation. Recovery was delayed when aggressive retry logic and a latent VS Code bug caused a tenfold traffic surge to the Copilot Token Service, which was eventually stabilized by throttling requests and reducing gateway retries.
