Api::V1::VideosController#create (avg 10104ms, max 10104ms)

What Happened#

2026-06-25 14:31 KST에 ap-southeast-2 리전의 cupixworks-api에서 POST /api/v1/videos 요청 1건이 10,104 ms 동안 대기한 뒤 500으로 종료되었다. 응답을 끊은 직접 원인은 Faraday::TimeoutError: Operation timed out after 10002 milliseconds with 0 bytes received로, Elasticsearch 클라이언트에 설정된 request.timeout: 10초 한도에 정확히 걸렸다. 동시간대 같은 인스턴스/리전에서 다른 500이 관측되지 않아, 1회성 Elasticsearch slow response/네트워크 이슈로 판단된다.
