WWV Broadcast Outages
If any network operators still use WWV for time synchronization. Due to an electrical up-grade, Radio Station WWV will be off the air on all frequencies on February 21 and 22, 2017. The outages will occur between 7:00 AM and 5:00 PM Mountain Standard Time, and will not exceed 8 hours in duration each day. https://www.nist.gov/pml/time-and-frequency-division/time-services/wwv-broad...

I wouldn't expect this to cause any serious synchonization problem; anyone using HF for time has to have the ability to hold over for a miniumum of several hours anyway due to the vagaries of normal shortwave propagation. (Even 24-48 hour disruptions aren't uncommon after a large solar event.) That said, I and many others "still use" WWV -- there aren't exactly a surplus of suitable backup methods to GPS these days. But if anyone needs it, consider using the fine HF time service provided by our friendly neighbors to the north: http://www.nrc-cnrc.gc.ca/eng/services/time/short_wave.html --msa
