Masking "problems" of a big ISP and yet creating problems of their own. Have you seen completely multi-transited "tier2 networks" flapping hard core?
So, it is not about tier-1 vs tier-2, it is about ISP specialized on cheap acvcess and ISP specialized on quality access. Is COGENT (for example only - I have nothing against them) tier-1 ISP - may be; are they high quality ISP - in NO WAY (they just provide bandwidth to nowhere without any clue).
Non-sense. James

In fact, I would posit that a Tier 2 withmultiplyredundant transit to all of the Tier 1s could theoretically have better connectivity than an actual Tier 1. The Tier 2 transit providesflexibilitythat the transit-free Tier 1s do not have. Just my opinion. Anyway, it has been my experience that most (but not all) of the customers that want to "multihome" are _really_ wanting either: A. geographic/router redundancy. or B. easy renumbering. Geographic redundancy can be done within a single AS and IP block. They just don't know to ask it that way. (And easy renumbering will eventually be solved with v6. Eventually.) The demand for multi-homing might not be as great as suspected. John
