Usage Policy Open. Abusers will be KoD-ed or firewalled. Restricted. I do not know how much NTP traffic this little box can take, so there are restrictions. If you want to sync to it, let me know your IP addresses and/or subnets. Open. Abusers will be firewalled.
IPv6 No No No
Location / Connectivity
Southeast London; Zen ADSL
NTP Pool Member No No Yes (Europe, UK)

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).
