Evaluating Tier 1 Internet providers

Clued-in support is a good criteria.  (I've been using a broker for some of
my connections and there was virtually no value-add there, especially in the
prefix-list modifications, and a liability in other MACs)

That's a good point with the Tier 2 providers.  So that begs the question,
why wouldn't I just get my upstream from a Tier 2?  (Because my management
is under the perception that we're better off with Tier 1 providers, but
that doesn't mean their perception is accurate)

much appreciated,
Eric Louie

I would add:

 - presence of staff in key locations (if 60 Hudson is a critical location
for you, find out whether there's someone regularly present in or near the
building to clean fibre and help run loopback tests when you need them)

 - expected time to clue when calling the support number (bonus points for
being xkcd-806 compliant)

 - time taken to turn around BGP import filter changes

 - response you can expect when you call one day and say "our 10GE is maxed
out with inbound traffic from apparently everywhere, it has been going on
for an hour, please help"

 - billing accuracy, and turnaround time for questions raised about invoices
received

A lot of this comes down to conversations in the NANOG bar with people who
have war stories to share. To that extent, I think "reputation" is a good
indicator, so long as your sample size is reasonable, and depending on the
amount of beer involved.

One other thing to think about -- Tier 1 providers are transit free, so your
"can be reached by an IP packet from" is naturally limited to specific
peering relationships with other Tier 1 providers. Tier 2 providers (those
who buy transit from a suitably-diverse set of Tier 1s) can insulate you
from route fade due to peering spats.
