a question about the economics of peering

BTW, public IXen in Europe don't tend to be congested. Whether this is
the result of better management, or of lower traffic volumes

Possibly, they also tend to be member owned so people have a stake in
making them work whereas a commercial IX may have other priorities

We have virtually zero visibility into what's going on inside
commercial IX compared to the data we see in member organisations -
it's hard to hide stuff from the members

Doesn't mean commercial is bad though
