  1. Resolved

    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.<br /><br />The incident was mitigated when the downstream provider recovered, after which we confirmed that the tool’s success rate had returned to normal.<br /><br />We are improving the tool’s resilience and failure handling to reduce the customer impact and duration of similar incidents.
