ElementRecordsController missing HTTP timeout — Siteinsights API delay amplification
What Happened#
2026-05-26 04:13~05:35 UTC 사이에 Api::V1::ElementRecordsController#index 엔드포인트에서 평균 2499ms, 최대 2722ms의 응답 지연이 ap-southeast-2, us-west-2, eu-central-1 3개 리전에서 발생했다. 이 컨트롤러는 외부 SiteInsights API Gateway/Lambda 서비스에 동기 HTTP 프록시 호출을 수행하며, 하류 서비스의 응답 지연이 Rails 요청 전체 지연으로 전파되었다.
