Earlier quoted context omitted.

maybe your upstream doesn't validate DNSSEC?

maybe? I'm using PiHole and 8.8.8.8/1.1.1.1 as upstream, and both options show "DNSSEC" next to their options in settings, so I assumed DNSSEC was enabled (unless I have to enable this somewhere else as well?)

That's weird cause 8.8.8.8/1.1.1.1 will already answer with SERVFAIL right now, unless the domain is still in the cache.

its gonna be all .de domains once caches dry out, anything that still works right now is bound to eventually fail until the underlying issue is resolved

Any .de domain with DNSSEC

Unfortunately, even domains that did not have DNSSEC enabled earlier today are affected.

We observed issues on a non-DNSSEC .de domain at 19:45Z and confirmed around 20:12Z it wasn't just us, but also more high profile domain names.

https://status.denic.de/ says "Partial Service Disruption" for DNS Nameservice now. EDIT: it says "Service Disruption" now

At least they have some humor left. Edit: Now even the humor is gone.

Can only be topped when the status page is not reachable anymore :D

EDIT: called it...

Crazy. I can't remember an incident like this ever happened before and it's still not fixed? .de is probably the most important unrestricted domain after .com from an economical perspective. Millions of businesses are "down".

It's Germany, pessimistic time estimation + 1/3 and you are in a realistic time frame for the issue being resolved.

It's night. Somebody has to fill a form to approve night work first.

INVESTIGATING

Frankfurt am Main, 5 May 2026 – DENIC eG is currently experiencing a disruption in its DNS service for .de domains. As a result, all DNSSEC-signed .de domains are currently affected in their reachability. The root cause of the disruption has not yet been fully identified. DENIC’s technical teams are working intensively on analysis and on restoring stable operations as quickly as possible. Based on current information, users and operators of .de domains may experience impairments in domain resolution. Further updates will be provided as soon as reliable findings on the cause and recovery are available. DENIC asks all affected parties for their understanding. For further enquiries, DENIC can be contacted via the usual channels.
