The problem are not "slow transoceanic links" per se as I hardly
experience any congestion issue on those nowadays.

The problem is the delay those longhaul links generate, and thus
limit TCP performance massively.

Ever seen FTP with more than about 3mbit/s transatlantic? No? This is
NOT because of a lack of bandwidth!

So the aim of seperating trackers is not avoiding small bandwidth links,
but high RTT (delay) links, which directly affects TCP performance.
