Diverse entrances are standard in telecom hotels and major data centres. 

I don't think you have made the redundancy argument for satellite particularly given the relative expense of 
transponders vis-a-vis private line capacity on the major routes. However, it could play a role in some cases. Also 
satellite's latency is simply too high for the applications of financial firms. Every millisecond of delays costs 
millions in lost trading profits over the course of a year. 

The real failure is relying on just one data centre for backup. Most of the smarter European and North American 
financial firms now have data centres in both Europe and North America and replicate their data across TransAtlantic 
links. A lot of large file transfers at night for the hedge funds.
