CF does not own their 185 datacenters across the globe. These are rented
spaces. Some are not affable to GPS setup (no rooftop access or GPS farms
etc.). Even if they were there is extra cost for GPS setup, rent,
maintenance,  requires traveling to remote physical locations if something
goes wrong and more... CF has 185 datacenters and so the cost and effort
accumulates. Using external stratum 1 servers was a more reasonable option.
CF made sure that their servers are connected to the closest available
authenticated S1s.
Buying their own S1s is definitely on the table.

Best,
Aanchal.
