I'd contend that using Cogent is a good way to reduce your cost of
doing business while maintaining an acceptable level of service, not
to necessarily improve reach. If your network absolutely must have the
best routes you may be better off adding some other providers

Best regards, Jeff

Aside from the occasional peering wars i've never had or witnessed any

Plus if you had direct connectivity to Cogent, their peering status with
others wouldn't affect you anymore. Personally, I've seriously
considered this as a reason to get a connection from Cogent.

If you are not single-homed, you have no issues reaching Cogent even
during a "peering war" - unless Cogent depeers / gets depeered from
-both- (all) of your upstreams at the same time.  So what value is there
to add Cogent?

The value is, that Cogent pretty much is the cheapest transit you can
get out there vs. paying a premium for carriers that have less clue and
more outages.

Sorry for being imprecise.  I meant that adding Cogent does not
significantly improve your reachability.  Choosing to buy from Cogent
because they depeer / get depeered occasionally is silly, IMHO.

To be clear, I am making no comment on Cogent's overall performance.  If you
find value in adding a provider for other reasons (cost, performance, etc.),
I would not argue against it.
