But can't NTP server downtime cause a disaster?

One (amongst many) NTP server going down creates less issues than an NTP server spreading wrong time.

General rule of thumb: a misbehaving/slow server in any well-architected distributed system is vastly worse than a dead server.

technically if you have 3 or more sources that would be caught; NTP protocol was designed for that eventuality

If your application is so critical that NTP timing loss causes
disaster
and your holdover fails in less than a day and you aren't generating your own via gps, you are incompetent, full stop
