Yes .. that we do … but we can't do it against our peers which is where the 
crap comes from :)

Last time this happened we had 2Gig of "crap" come in via Level 3 with the rest 
of the cruft leaking in via Datahop

Today it has all (pretty much) come via LINX

And I'll be really happy when LINX re-enable flow stats so we can see who's at 
fault :)
