It's indeed not ideal, although generally not as bad as you are 
currently seeing. However moving it would be way too costly at this 
point, and Tampa also has a few advantages, such as being pretty cheap.

The situation can be mitigated quite well by putting Squid caches in 
sensible places. Maybe we can move all of it in a few years if/when we 
have more cache reserves, we'll see.

I am actually glad that these days we get to complain about the speed of 
light as the bottleneck, instead of other capacity problems within our 
cluster...
