CUHK opens its v6 Stratum 2 NTP Server for public

In our department, we have some equipment that are not dual-stack and they ride on IPv6 only.  It is hard to provide a good system clock to these system since there is not yet an authoritative NTP server.  I just learn that CUHK has released its v6 Stratum 2 NTP Server (ntp.cuhk.edu.hk)  for public use.  Thanks to Cheng Chee-hoo of CUHK.

The Hong Kong Observatory will provide its v6 NTP Server by the end of 2011.  For the time being, I still have to use the one offered by CUHK.
