Cloudflare Outage Timeline

Database permission issue caused bot-detection to generate oversized config → cascading network failures

Missing environment variable during credential rotation → invalid keys broke R2 writes & degraded reads

Network performance issue → regional reachability failures (HubSpot, Zoom)

Network-wide failure → thousands of websites offline & incorrect Bitcoin price data

DNSSEC validation failure → expired root zone signature during ZONEMD rollout → 1.1.1.1 SERVFAIL spikes

Code release corrupted service token metadata → Zero Trust + CDN control plane issues

Critical internal incident → broad connectivity failures & 500 errors

CenturyLink network failure → huge spike in HTTP errors across Cloudflare data centers

Misconfigured backbone router broadcast faulty routes → major sites offline

Verizon BGP misrouting → massive traffic redirection → widespread outages
