> Tier 1 means you don't buy transit, no? Presumably it follows that tier 2 networks do buy transit. Therefore, why would anyone buy service from a Tier 1 network except for other network operators?
This doesn't match with the reality that providers who are Tier 1 seem to get some very big companies as customers. Why would they do that if Tier 1 networks offer a substandard service? Is this a scandal in the making? --Michael Dillon
