Ping & traceroute
If you suspect a network problem between the monitoring system and your server, it’s helpful to have a traceroute from your NTP server to the monitoring system. You can traceroute to the monitoring network using 126.96.36.199 or 2607:f238:2::ff:5.
You can ping or traceroute from the monitoring network using HTTP, with:
curl http://trace.ntppool.org/traceroute/188.8.131.52 curl http://trace.ntppool.org/ping/184.108.40.206
