there are restrictions.
If you want to sync to it, let me know your IP addresses and/or subnets.

IPv6 Note: IPv6 connectivity is through a
Hurricane Electric tunnel, so you will
see additional latency and jitter using IPv6 compared to the same server on IPv4.
If this matters to you, append "-ipv4" to the hostname (eg use: a-ipv4.ntp.alphazed.net).
