CDN Acceleration 502s on DNS Records
Resolved MinorIncident Report
Summary AI Generated
Bunny.net experienced an issue where newly created CDN accelerated DNS records resulted in 502 errors for affected domains, lasting 26.6 hours. The problem was caused by a backend process discrepancy that created zone ID mismatches on new CDN accelerated zones, while existing pull zones and previously created CDN accelerated zones remained unaffected. The incident was resolved with a hotfix deployment and processing of the accumulated backlog of pending updates.
As a continuation of our DNS issues last night, we are currently investigating an issue when newly CDN accelerating a DNS record results in CDN 502s for the domain in question.
Existing pull zones and pull zones not created via CDN Acceleration are not affected. Existing CDN Accelerated zones are also not affected.
