503s for >1% of http traffic bound for workers
Hey all, in HTTP Traffic Analytics for the past 30 days we’re seeing ~1.5% of requests to our worker routes return 503 (Service Unavailable), but no errors show up in Workers Observability, and we’re well under the 100k/day limit (~4k–5k/day). Logs are clean
Workers return a simple HTML page if pathname matches, otherwise return fetch for the original request. 503s show up for the same URLs that work normally
Can Cloudflare return 503s before the Worker runs, even under quota? What else could cause this?
