Resolution Issues for .de Domains
Resolved MinorIncident Report
Summary AI Generated
Cloudflare experienced DNS resolution issues for .de domains lasting 17.9 hours, caused by DNSSEC signing problems at DENIC (the .de domain registry). The incident affected Cloudflare Sites and Services and Recursive DNS, impacting users' ability to access German websites. Cloudflare resolved the issue by temporarily disabling DNSSEC validation for .de domains on their 1.1.1.1 resolver, allowing .de domains to resolve normally until DENIC fixed their signing problems.
We are observing issues with authoritative resolution for the .de TLD.

The issue has been identified as a DNSSEC signing problem at DENIC, the organization responsible for the .DE top-level domain. Cloudflare has temporarily disabled DNSSEC validation for .de domains on 1.1.1.1 resolver (as per RFC 7646) in order to allow .DE names to continue to resolve. DNSSEC validation will be re-enabled when the signing problems at DENIC are known to have been resolved.
