  and each one of those 1U units costs how much, and can feed reference signals to how many individual end-point servers? It doesn't scale to a massive hosting/hypervisor operation. products like the one linked above are priced and intended for providing timing to crucial core network infrastructure. Such as if you're an ISP with a POP that has a 1+1 pair of Juniper MX960 at the main IX point in a major city. Where the ISP would then have its own set of NTP servers serving as internally-accessible-only stratum 2 to all of their other network equipment that is topologically nearby within the same AS.

    >and each one of those 1U units costs how much It depends on what capabilities you want. A good oscillator with GPS discipline capabilities would cost between $100-$10000 depending on specifications. In particular, if you want it to have high stability with time and temperature when GPS fails you must spend much more money. >and can feed reference signals to how many individual end-point servers? In theory one of these units could feed a whole datacenter (thousands of endpoints), if you also purchased enough cabling and distribution amplifiers.
