I hear ya but this would more than likely be something like a really sloppy human error such as following the wrong process vs. a miscommunication otherwise I would expect these outages to be much more frequent. I do remember when a fat-finger at UUNET took out most of the internet long ago but that was a human error and is a bit harder to have the same impact today.

To me a communication error implies someone followed erroneous instructions without asking the obvious, " ... but isn't this a big business that is still live and why don't I have a legal order in my hand?" In fairness this did happen recently with he.net because a sub-domain was reported but it was done intentionally even if they failed to do even basic due diligence. After Covid I would expect most people would know zoom.us would be in use by a lot of people whereas only specific groups of people would know what he.net is.

I am curious if the process has changed due to laziness and now registrars can just select any number of domains and click a button to place them on hold without management or executive approval. If so that should be in some audit trail and should require confirmation and approval by a senior leader.
