attacker convinces you that they are actually multiple servers, so that you
think you are using a large number of independent peers, but in fact you have
a single point of failure (where the attacker turns off all their machines at
-once). Large grids, with lots of truly-independent peers, will enable the

overhead because each peer needs to know something about every other, and the
rate at which peers come and go will be higher (requiring network maintenance
traffic). Also, the File Repairer work will increase with larger grids,
