  • Description
    Due to a fault, there is currently limited availability to the recursive DNS resolution for "de" domains.


  • Resolved
    The DeNIC resolved this issue. We removed the negative trust anchor from our recursive DNS servers. ".de" domains are by now resolved again including DNSSEC validation.

  • Monitoring
    Due to the continued issues we have temporarily disabled DNSSEC validation for ".de" domains.

    Resolving ".de" domains that are using DNSSEC via our recursive DNS servers should work again.

    We are monitoring the situation and hope to be able to remove the negative trust anchor soon.

  • Investigating
    It seems like the fault is related to DNSSEC issues with "de" domains on a registry level.
