Degraded Performance on WAF Cluster 39
Affected: Europe WestEurope Central
Timeline · 2 updates
- investigating Feb 06, 2026, 11:50 PM UTC
We are currently mitigating a network-related issue affecting a subset of traffic originating from the Paris (EU) region. As part of this mitigation, a specific IP associated with Cluster 39 has been temporarily blackholed in the Paris PoP to protect overall platform stability. Impact: Some customers accessing their websites from Paris and parts of the EU may experience connectivity issues. Traffic from other regions remains unaffected. No data loss has been observed. Mitigation Actions: Cluster 39 has been temporarily blackholed in the Paris PoP as a containment measure. Impacted customers may experience service disruption in that region until the issue is fully resolved. Support: If you are experiencing issues accessing your site from the Paris/EU region, please contact Support so we can promptly move your site to an alternate cluster.
