Client‑Side DCDN Disaster‑Recovery Drills and Automated Testing at Bilibili

Bilibili performed client-side DCDN disaster-recovery drills using a self-built HTTPDNS to simulate DNS, CDN, and SSL faults; automated scripts across Android, iOS, and Web injected errors, measured rendering latency, validated immediate downgrade to commercial services, refined fallback strategies, and demonstrated near-zero user impact during a real network incident.
