This page: https://tf.nist.gov/tf-cgi/servers.cgi shows that NIST has > 16 NTP servers on IPv4, of those, 5 are in Boulder and were affected by the power failure. The rest were fine.
However, most entities should not be using these top-level servers anyway, so this should have been a problem for exactly nobody.
To say NIST was off is clickbait hyperbole.

IMHO, most applications should use pool.ntp.org
