When I still worked at Equinix, we had NTP chimers in all the datacenters
which customers could either hardwire (IRIG-B, etc) or peer with NTP.
However, it seemed that people who cared about time always wanted to
have their own NTP chimers which they owned and controlled. The
concern about relying on third-parties, and even the theorotical
NTP attacks.
