Ask/pay/rent for roof access for the antenna, it's not large but it does work better with an unobstructed video of the sky. There's also the question of how many stratum=1 time sources a given datacenter needs. if there's someone else with one it should be fairly unintrusive to share.
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.
