    Here's a thought:

    The fact that people are experiencing issues with DE sites and asking if CloudFlare is down speaks volumes about the stability of DE ccTLD and the broader DNS compared to big cloud providers.

    @rysiek last notable outage at denic was almost 16 years ago, when they moved servers from amsterdam to frankfurt.

              @yetzt Since that day, all my domains have name servers assigned, which are under two distinct TLDs. And this is the reason, that all my domains (except for .de) still resolve at the moment.

                DENIC's status page:
                https://status.denic.de/

                Screenshot below in case you're not able to load it (as I said, stuff is going to be intermittently failing).

                @rysiek fortunately the status page can still be accessed via https://denic.status.io

                    @rysiek@mstdn.social True experts questioned their home infra first, because that is obviously the most stable culprit ​​

                      @packetcat ooof.

                      There is going to be a lot of stuff to learn from the post-mortem.

                      @rysiek @packetcat It looks like circular dependencies are going to be a big part of this...
