gpsd server located in Singapore.
The server runs the master branch of both the gpsd and NTPsec projects, so may frequently be restarting.
It is a member of the
NTP Pool since 2008, and has been available on IPv6 since 2012.
It supports NTS, and you are encouraged to use that, for some additional security.
