    We are currently aware of an issue affecting DNS resolution for many .de domains. Customers may experience issues reaching websites or services hosted on affected domains when using certain DNS resolvers. The root cause appears to be a zone signing issue at DENIC (the .de registry), which causes DNSSEC-validating resolvers to return an error when resolving affected domains. https://status.denic.de/ shows this as a "Service Disruption". The issue is outside our control and a report has been submitted to DENIC.
