The definition of tiered support system changes from company to company. Ref: Technical support - Wikipedia, the free encyclopedia
Generally, a Tier 1 support personnel will be directly interacting with the user and problem, and has little to no training.
As the Tiers go up, more trained personnel specialized in the problem at hand approach the problem and try to fix, before moving the issue upward to the next tier.
Eg... Tier 1) Help Desk. Tier 2) Desktop Support Team. Tier 3) Network/Server/Phone/Specific team. Tier 4) Specialized vendor support.

He's not talking about levels of support. The question is regarding the term used to define ISPs in terms of their internet transit.

I've read that the lines are very blurred as far as which ISP is which tier and it's kind of an arbitrary distinction. -

Page 5 in the BGP book by OReilly gives a pretty decent description on the 3 tiers. It is not real long, and the author does mention, like Colby said, that the lines are kind of blurred (especially between tiers 1 and 2). He says the main difference in the two is that tier two is usually geographically limited whereas tier 1's are not. -

If you have to ask yourself "Am I a Tier 1?" You're not a Tier 1.RFCs: the other, other, white meat. -

From the top of my head, The Tier 1 networks are: Level3, Abovenet, ATT, VZ, Global Crossing, Reliance, Qwest, and NTT. But there is no official list of the 'tier 1 networks', and the term can mean different things to different people.
