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. <br /><br />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. <br /><br />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.
