What we are seeing is clearly an act of malice. We need to be honest about that. Trying to obfuscate what we are seeing helps no one. We should use plain English and talk in a straightforward way about what is happening.
I disagree. The nameservers still respond to requests on 53/tcp. It seems like someone messed up a firewall configuration or rolled out a bad server configuration. Shit happens - maybe exacerbated by the DOGE insanity. But there is no indication that this was done on purpose.
