Exchanges that matter...

Country wise?

Difficult to divide up traffic sourced in the UK from traffic sourced
outside teh UK just at the mo, but we send the vast majority of the
rest to the states. I'd guess 50% to LINX (UK), 40% to US one way
or another and 10% to Stockholm SE. The figures are not too easy to
get as we are transitting US networks back to Europe too.
