Design and Implementation of Bilibili's Emergency Response Center for Incident Management

Bilibili’s Emergency Response Center (ERC) unifies incident detection, rapid response, precise scoping, and coordinated recovery through multi‑dimensional alerts, automated collaboration, standardized updates, and post‑mortem analysis, targeting 1‑minute detection, 3‑minute response, 5‑minute scoping, and 10‑minute recovery, which has cut MTTR, achieved over 80% automatic recall accuracy, and met more than 60% of its 1‑3‑5‑10 performance goals.

Guidelines for Incident Postmortem and Fault Review

The incident postmortem guideline advocates a dialectical view of failures, rapid low‑severity recovery, and a structured process—covering background, impact scope, timeline replay, deep root‑cause analysis, SMART improvement actions, responsibility assignment, and PDCA‑validated closure—to enhance system resilience, team anti‑fragility, and knowledge sharing.
