I have seen things here similar to this very often / permanently:

cablecom  to UK/NL often via level3 and washington instead going directly

may something to do with UPC and partnership with level3 - and the "Nonpartners" of level3.

"we do not peer with you" politics ?!

imho   cogent vs level3

below a trace to system in london from cablecom home:

Anyone else seeing this... do we have a new peering spat or is it just a
random routing issue?
