NIST Warns of NTP Inaccuracy After Blackouts Across Colorado
NIST faced issues with NTP servers after a power outage in Boulder caused atomic clock drift. A staffer contemplated shutting down servers to prevent spreading incorrect time, but a generator failure complicated efforts. Despite the outage, NIST maintained operations using backup power, reporting minimal time deviation. Users dependent on Boulder’s time were advised to use alternate sources. By December 21, services were restored, showing stability with only slight clock errors, emphasizing the importance of using multiple time sources.
