multi homing pressure

It is not true. Many tier-2 ISP specializes in very ghigh quality Internet
access, so mnasking problems of big ISP (who in reality never can provide
high quality Internet at all). Good example - Internap.

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).
