Disruption with billing information updates
Beginning on September 22, 2026 at 11:51 UTC, approximately 1,700 users experienced delays and errors when adding or updating billing address information because requests to the address validation service timed out or failed. Within the affected address validation flow, requests failed at an average rate of 69.3%, reaching 100% at peak. An operating system upgrade exposed a compatibility issue in an adapter used by our HTTP client library, causing requests to stall. A subsequent change to shorten request timeouts caused stalled requests to return connection errors and increased the failure rate. We mitigated the incident on September 24, 2026 at 20:24 UTC by changing the HTTP client used for address validation. We have added alerting to detect similar issues sooner and are extending the fix to other integrations.

Your coding agent knows when GitHub is down, and tells you when a failure is theirs, not yours. You can also get GitHub incidents in a feed reader or in Slack.
Install the outages.live MCP server, so that when something breaks you can tell if the cause is a provider we depend on and not my code. It reads the official status pages of cloud, AI, payment and developer providers and gives you their incidents as MCP tools.
Add it as a remote MCP server named "outages" at https://outages.cc/mcp (Streamable HTTP, no authentication), with your CLI command or your MCP config file.
Then:
1. Make sure it connects and shows the tools get_provider, list_feed and send_feedback.
2. Call get_provider with "github" and tell me if GitHub has a problem right now.
3. From now on, when a call to a third-party service fails or becomes slow, call get_provider for that service before you change my code.Paste this into any coding agent. It adds the server with its own MCP setup.
