Cloudflare Page Rules HTTP Redirects Failing on Worker Subrequests

What happened

Cloudflare reported an ongoing incident with Page Rules where HTTP redirects are not triggering as expected on worker subrequests. The issue was identified on May 1 at 11:05 UTC, with Cloudflare implementing a fix after initially investigating the problem at 10:53 UTC. The company stated they are working to understand the full impact of the failure. Page Rules are commonly used by enterprise websites to manage URL redirects, caching behaviors, and security settings.

Business impact

Failed redirects can break critical user journeys including checkout flows, product pages, and marketing campaigns, directly impacting revenue. Sites using Cloudflare Workers with Page Rules for redirect logic may experience broken links and poor user experience until the issue is resolved.

Background

Cloudflare Page Rules allow website operators to configure how their sites handle specific URLs, including redirects, caching, and security policies. Many enterprise websites rely on Page Rules combined with Cloudflare Workers for complex routing and redirect logic, particularly for international sites, A/B testing, and legacy URL management.

What this means for your team

Immediately test critical redirect paths on your Cloudflare-hosted sites, especially those using Workers for complex routing logic. Document which redirects are handled by Page Rules versus other methods to enable faster troubleshooting during outages. Consider implementing monitoring for key redirect chains that affect revenue-generating pages.

What to watch

Monitor Cloudflare's status page for resolution confirmation and any follow-up guidance on affected configurations. Test redirect functionality once the fix is deployed to ensure normal operation resumes.
