Not so. We have moved on from such large time uncertainties in networking in the last 10 years, at least for specialized applications.
Also do not confuse the reference clock being slow, and the time propagation across the global network (ie Internet) being slow.
It is fine for the NIST clock to be inaccessible to the wider network for small periods of time, which would inevitably introduce drift on the downstream systems. Once those systems reconnect to NIST, they could correct themselves.
How a Power Outage In Colorado Caused US Official Time To Be 4.8 Microseconds
4.8 microseconds what? Longer, shorter - wider, thinner? Unless... (*gasp*) Time is now 4.8 microseconds. /s :-)
