Neither network has transit. What other path is there to take?

Then somebody (not clear who) apparently took explicit steps to stop the traffic from taking these other paths. Surprising. Severing a peering relationship is one thing, purposely filtering large swathes of the Internet over other all links is quite another.As I said, this is surprising behaviour, but not simple de-peering.

Why is it surprising? Sounds more like a repeat performance to me.Back when Level3 depeered Cogent, it was said that Cogent was already buying transit from Verio to reach at least some networks they weren't peering with. After the depeering, why didn't Cogent get to Level3 (and vice versa) via Verio?
Was the reason ever made public?
Tier 1 has enough peering relationships with enough other Tier 1 networks that they can always buy temporary transit privileges over an existing link.
Tier 1 means you don't buy transit, no? ---------------------------------------------------------------------- Jon Lewis | I route Senior Network Engineer | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________
