ISPs in Europe or Asia pay, as far as I know, about $250K/Year 
for a T1 line to the U.S. (for the line only, not for the internet 
connection).

On the other hand, traffic could have been reduced by a significant 
factor by using a large cache in the proxy http and ftp server. I know

that the academic network in the UK has a cache of 6 machines with 
16GB each and they reach 60% hit rate.

It is my guess that by using a huge cache, say 1TB (1000GB), it is 
possible to get 90% hit rate, i.e. to save 90% of the international 
lines cost. The cost of 1TB may be about $200k, so it seems a very 
good investment.

Where am I wrong ?   

Does anyone know of some research done in this field of knowing 
how large should a cache be in order to reach 90% hit rate ?

Thanks,
