IPv6 network time service available now from the Hong Kong Observatory

IPv6 NTP service is available from the Hong Kong Observatory (HKO) now at "time.hko.hk", the public announcement is at:

OFTA and CUHK have been helping the tests and configurations in the past 3 months. We are happy to work with HKO colleagues and share experience on technical issues of IPv6. This IPv6 NTP system is highly resilient, running dual-stack with v4 and v6 redundant links from two different ISPs.

It took 27 months from my first proposal to HKO to successful implementation. A great feeling of relaxation, finally.
