"This block was the result of a communication error between Zoom’s domain registrar, Markmonitor, and GoDaddy Registry, which resulted in GoDaddy Registry mistakenly shutting down zoom.us domain. "
Something is fishy about this. A communication error would not result in a domain being placed on hold. On hold is usually the result of a legal order or in the case of the .us TLD a nexus compliance violation. I've transferred thousands of domains from assorted dodgy registrars into MarkMonitor and can not even imagine a scenario where a miscommunication results in a domain being placed on hold.
Every place I've been we measured such weirdness outside of the 95'th and 99'th percentile. Anything out of common occurrence beyond the 99'th could be weird or interesting or fascinating. I still wish I could share the incident of a single NIC on a single server taking down an entire data-center, that was both weird and fascinating.
If there is a "default" then "everything else" is not weird. The conclusion is "this thing doesn't work most of the time so it wouldn't be weird if it doesn't".
