Disruption with some GitHub services
Final update
On July 16, 2026, between 08:50 UTC and 09:50 UTC, the GitHub MCP Server’s web_search tool experienced elevated failures. The average error rate was 42% and peaked at 82% of requests to the tool. Other GitHub MCP Server tools were unaffected. This was caused by degradation at a downstream web search provider. The incident was mitigated when the downstream provider recovered, after which we confirmed that the tool’s success rate had returned to normal. We are improving the tool’s resilience and failure handling to reduce the customer impact and duration of similar incidents.
