It's actually very easy to explain. The InterNAP Flow Control (FCP)
was designed to route traffic via the cheapest link available provided
the link is within an operating range. Over the years the PNAPs have
preferred different transit providers based on the underlying
contract rate - but what rate could possibly be better than free(1)?
So as time passes you will more than likely see more and more of
AS22212 in your path.

1. Peering is not free, but much less expensive than paying ATT.

PNET (AS22212) is looked upon by InterNAP's PNAPs (its various ASes) as just
another transit provider in the mix.
So yes, InterNAP technically peers (under AS22212), but there is no
guarantee its various PNAPs would choose that path, depending upon a number
of factors.

Subject: [NANOG] Purpose of Internap's PNET AS22212
Can anybody shed some light on Internap's PNET AS22212? Specifaly how it
relates to their PNAP architecture? Is Internap now doing peering? I was
under the impression that their entire business model was based around
isolated PNAPs and being a backboneless provider. Attempts at getting an
explanation from Internap have been fruitless.
