How a power outage in Colorado caused U.S. official time be 4.8 microseconds off

TLDR

A power outage at the National Institute of Standards and Technology (NIST) in Boulder caused U.S. official time to be 4.8 microseconds off. While this error is too small for the general public to notice, it could impact critical infrastructure, telecommunications, and GPS signals.

Windstorm + generator failure at NIST in Boulder caused a 4.8-microsecond drift in official U.S. time.. tiny, yet a big deal for precision users.
