Cloudflare Multiple Service Outages April 15-16: Workers, R2, APAC

What happened

Cloudflare experienced six separate service incidents between April 14-16, affecting multiple core services used by enterprise websites. The most significant incident caused elevated error rates for Durable Objects and R2 buckets specifically in the APAC region, lasting from 17:33 to 20:47 UTC on April 15. Simultaneously, Cloudflare's global network experienced increased HTTP 5xx errors from 19:14 to 22:56 UTC the same day. Additional incidents affected Workers API latency, billing systems for Argo Smart Routing, container scheduling, and WARP device configurations.

Business impact

Enterprise teams relying on Cloudflare's edge computing and storage services faced potential revenue loss during peak APAC business hours, with elevated error rates directly impacting user experience. The simultaneous HTTP 5xx errors would have triggered monitoring alerts across affected websites, requiring immediate incident response from on-call teams. Organizations using Workers for critical business logic or R2 for content delivery experienced service degradation during a concentrated 8-hour window.

Background

Cloudflare's Workers platform and R2 storage service have become critical infrastructure for enterprise edge computing and content delivery strategies. The clustering of six separate incidents within 48 hours is unusual for Cloudflare, which typically maintains high availability across its global network. APAC region incidents are particularly concerning for multinational enterprises as they often coincide with peak traffic periods for Asian markets.

What this means for your team

Review your Cloudflare dependency mapping and ensure you have fallback mechanisms for Workers-dependent functionality, especially if serving APAC traffic. Implement monitoring specifically for 5xx error rate spikes from Cloudflare origins, not just your application servers. Consider geographic redundancy for critical R2 storage buckets and test your incident response procedures for simultaneous multi-service degradation scenarios.

What to watch

Monitor Cloudflare's post-incident analysis reports for these clustered failures, particularly any indication of underlying infrastructure issues. Track whether similar incident patterns emerge in other regions, which could signal broader platform stability concerns.
