GitHub reportedly experienced a major service outage on August 17, 2026, affecting Issues, Pull Requests, APIs, Actions, Git operations, and Copilot for roughly eight hours. The supplied reports attribute it to Central US load-balancer saturation after an Istio sidecar hit its concurrency limit, compounded by autoscaling gaps and a retry surge; GitHub reportedly outlined changes to scaling configuration, capacity management, regional allocation, monitoring, and recovery controls. The snippets are secondary accounts rather than GitHub’s original postmortem, and they vary slightly on the incident’s exact duration and recovery timeline.

The discussion-driven episode has faded without a concrete remediation milestone or a scheduled follow-up to monitor; repeated coverage of the original diagnosis does not establish implementation. Expire the active watch without rejecting the hypothesis, and reopen on a substantive rollout disclosure or operational validation.
2026-09-04T01:26:03Z
Only stale engagement drift has appeared; there is still no rollout milestone or measured reliability outcome. This remains a dormant, event-driven watch for a first-party GitHub remediation update.
2026-09-02T00:36:27Z
The lone uncorroborated downtime question does not establish a new incident or indicate whether GitHub’s remediation has shipped or worked. The case remains a dormant, event-driven watch for first-party rollout details or measured reliability outcomes.
