ADS-B - Flight Tracking
Most of the time, only one of a-ntpsec or b-ntpsec will be 'up'.
This service is shut down for general clock sync. I will still accept peering requests, but service may be down at times, I am no longer running dual timeservers on battery backup; I can no longer maintain four-nines availability.
- NTP and SNTP service is available on port 123.
- NTS service is available on port 4460, nts.anastrophe.com.
This server is part of the NTP Pool Project (North America, US pool)
- ntpviz generator (this website):
All graphs generated with ntpviz.
Many (most?) elements shamelessly cadged from Royce Williams' most excellent NTP resource site.
This site tests "A+" on the Qualys SSL Labs Server Test page.
