Hi, I work on the RIPE Atlas project (https://atlas.ripe.net/). We have more than 8000 probes world wide that can performance various types of measurements. Ping, traceroute, dns, http, but also ntp.
My plan is to start a measurement where all probes perform ntp measurements towards pool. Especially with the upcoming leap second, now seems to be an interesting time to start the measurement. There is almost a month to collect a baseline reference. And some system might announce the leap second early. My current plan is to have each probe run an ntp measurement toward pool.ntp.org every 15 minutes. A measurement involves looking up pool.ntp.org in DNS and sending 3 requests towards the first IPv4 address that is returned. (IPv6 capable probes would run a separate measurement to the first IPv6 address). In general, our raw measurement results are public. I'm writing this mail to get feedback from the pool operators to see if those parameters are acceptable, if this is the best way to run the measurement, etc. Philip Homburg _______________________________________________ pool mailing list [email protected] http://lists.ntp.org/listinfo/pool
