Issue

Due to a configuration error by DENIC, the company responsible for all .de domains, access to .de domains is currently disrupted, including gwdg.de, mpg.de and uni-goettingen.de. By taking countermeasures in the Göttingen campus network, the domains can be accessed again in the campus network. It may be necessary to restart the end device (computer, laptop, cell phone).

Technical details:
On the DNS resolvers of the GWDG (134.76.10.46, 134.76.33.21) the DNSSEC validation for DE domains has been temporarily switched off to avoid the wrong keys of DENIC. Access from other networks may continue to cause problems until the error has been completely rectified by DENIC.
