Satellite Internet and Banning WebSites

In a terrestrial internet, you would need to intercept and filter the traffic across some physical boundary around the network. From a network there may be a number of connections to other networks to assure alternative routing, even when some paths are blocked or congested, so blocking traffic for a particular web site is difficult.

In satellite internet, using a star network topology, you could block the traffic for a specific web site at the hub teleport. Such a hub teleport might have its own network connected by several alternative routings to terrestrial backbones or peering connections to other networks; each of these would need filtering. Mesh topology satellite networks are less common, but the possibility of routing traffic via alternative far end gateway earth stations provides more resiliance in the event of some paths being down. A rural community ISP in Africa might, for example, have three VSAT links, one connected to a USA teleport, one to a Europe teleport and one to a hub at the nation's capital city. Traffic would normally go via the "best-shortest-cheapest" route but in the event of any route failing the alternatives routes would continue to work.

Satellite internet access is expensive and to keep costs per user down the big outlink carrier bit rate is normally shared amongst many customers.  Streaming and 'greedy downloading' needs to be discouraged.
