I am unaware of any IXP that uses a smaller sampling period (presumably =
in an attempt to make their IXP look bigger) other than DE-CIX.
Is there another one?
And yes, DE-CIX is more than well aware everyone thinks this is .. uh .. =
let's just call it "silly" for now, although most would use far more =
disparaging words. Which is probably why no serious IXP does it.
