It's always DNS: Denic says sorry for crashing Germany's internet

Denic says the DNS blunder that brought most of Germany’s internet down on Tuesday evening is now resolved, and that websites should be operating normally after hours of disruption. The registry, which looks after Germany’s .de top-level domain, said the problems were first detected at 21:57 on April 5, but engineers rolled out fixes by 01:15. It said the issues were related to Domain Name System Security Extensions (DNSSEC), and that faulty DNSSEC signatures were distributed.
