Problem: Collisions

Server Sky arrays will eventually fill large regions of space. They will all be travelling in the same large pattern, in allocated orbits with the same period. Nearby server-sats will be moving at nearly identical velocities. However, an encounter with vehicles and structures that are NOT in the same orbit could be catastrophic.

Carefully positioned gaps in the clouds can be allocated to provide safe passage for the vehicles they might interact with. Given sufficient warning, server-sat arrays can be deflected out of the way of collisions with tracked objects.

Satellites in highly elliptical orbit

There are a few of these, such as the russian Molniya satellites. If they are well tracked, they can be avoided. If they are in 12 or 24 hour orbits, then regular gaps in the array can allow them to pass unhindered.

Server-sat launch buses

Gaps in the server sky cloud also permits insertion of new server-sats into the cloud. Launch buses can be maneuvered into same period orbits from below, just ahead of the server-sat array they will be "seeding". The server-sats they release will slowly maneuver backwards into the array.

Space Elevators

If space elevators ever come to pass ( launch loops are more likely ) they will pass through the orbital plane of the serversats twice a day. Gaps must be created for them. However, a failing space elevator cable will likely sweep through areas without gaps. In a densely populated server cloud, this may smash many server-sats, and the flying debris from those might damage more. Eventually, the non-synchronous debris will slow down to cloud velocity, but not before it bumps into a lot of server-sats. Cleanup after a space elevator failure will be expensive.
