Intermittent timeouts on Tokenization and Card Creation API endpoints

Update timeline

1. identified Sep 14, 2026, 04:20 PM UTC

   Beginning at approximately 07:05 UTC on September 14, some API requests have been experiencing intermittent elevated latency and timeouts, returning HTTP 504 errors. The affected endpoints are GET /v1/tokenizations, GET /v1/tokenizations/{tokenization_token}, POST /v1/tokenizations, and POST /v1/cards. Impact occurs in short windows of roughly 10 to 20 minutes, recurring periodically, and requests outside those windows are completing normally. Card authorizations and other API endpoints are not affected. The team is working to fully mitigate the issue.
