We are currently experiencing service degradation across multiple Downdetector platforms, including the API, Explorer, and consumer-facing sites. The issue is linked to an ongoing Cloudflare network incident that is affecting traffic routing and edge performance.

We have implemented workarounds for all Cloudflare-related issues, and services have now recovered. Cloudflare is also reporting improvement, and our temporary mitigations remain in place as a precaution. We are actively monitoring the situation, and all Downdetector services appear to be operating normally. Further updates will be provided if required.
