In case NIST servers are hard to reach, a metrologically defendable

I agree that this is a sensible answer from a technical perspective.
However has anyone else done this and passed SEC scrutiny? Remember that
US law is rules-based, not principles-based.
I am certainly not a lawyer and dont know what in this case is written in laws and
what is written in regulations, but if you are obliged to break the
regulations to comply to the law, you cannot be wrong...
Clearly another topic.
But personnally I would not hesitate long, since if
you do nothing you also break the rules by not being sync'ed.
Log the incidents, warn NIST, take countermeasures, justify them,
hard to find anything else to do in such a situation.
