What Happened#
2026-07-17 22:45 KST, cupixworks-api (production, us-west-2) 에서 model update callback 이 site-insights 이벤트를 Kinesis 스트림에 동기 publish 시도하다가 kinesis.us-west-2.amazonaws.com:443 로의 TCP 소켓 open 이 timeout 되며 실패했다. 단일 요청 1회 발생이며, 같은 초에 caller-level(Failed to create event) 과 SDK-level(Failed to put records) 두 개의 error 로그가 페어로 남았다.
