Peering problem with NSP

Well, when dealing with this off-line, kindly include
engineer at, because quite frankly, *I* have no
idea what you're talking about either.   Perhaps it's
too subtle for me.

That kind of information is worth sharing so that both
parties' shared customer is satisfied.  (And perhaps this
will be useful enough for people planning on multihoming
between you and other providers than SprtintLink that it
should be talked about in a more public forum with a view to
helping people understand all the complicated issues
involved in multihoming among several transit providing backbones.)

Say, I wonder if this'll get me accused of unprofessionalism
or disreputableness too?  It's been a quiet week; nobody has
ranted about me in far too long.

I do wish you'd feel free to ask us these sorts of questions directly.
We're more
than happy to provide you with an explanation, and an honest answer based
on the facts
will go a lot farther towards providing you with a solution, than open
speculation on a
mailing list. But feel free to solicit opinions.

Language used in networking can be a bit confusing, since some of the aspects of
networking are somewhat subtle. I will send you a more detailed
explanation, but I
wanted to set the record straight in this public forum. The reason we cannot
guarantee transit AS connectivity is a direct result of not being your default
connection. If you select us as default, we can guarantee transit access. The
particulars behind that are technical; I will fill you in off-line, since that
information is proprietary. And yes, it really does have a strong impact on our
backbone *design*.

[ BTW, Matt, we are iSTAR internet, inc. (formerly fONOROLA i*internet).
Please use
  our new name when referring to us, to avoid any confusion. ]

Frankly, it is this sort of unenlightened, baseless opinion that gives
Usenet its
deserved reputation. It certainly doesn't reflect the level of
professionalism that
a reputable NSP should display, on this list in particular.
