RE: carrier comparison

Hi all,

Just wanted to say thanks to all who replied on and off list to my original inquiry. 

I'd sum up feedback as follows:
-       Although Cogent has been surprisingly good for some, in general almost everyone agreed that it should never be 
relied upon as your main Internet provider. As a secondary link, they are a good value.
-       People had generally good feedback about Level3
-       Having one carrier provide service over another carrier’s fiber is generally not a problem. Sometimes it adds 
complication when things go wrong (and a couple people had some pretty extreme cases to share), but in general most 
people did not recommend shying away from this kind of relationship. 
-       Time Warner also received positive reviews in general as a carrier

I was also surprised how many small ISPs like us are on the NANOG list. I kinda assumed most of you were big operators 
that dwarf us. It's great to have received perspectives from both large and small operators.  

Thanks again, everyone. 

Adam

This is exactly what I thought had happened....The outage that affected you was one our two routers up-stream from your 
connection to that provider.

I am not trying to defend any Carrier, but there is no 'routing protocol' what will react to this kind of an issue.....

We don't get a default route from them. At the time of the outage my 
bgp session was up and I had a full routing table from them.  I didn't 
have much time to troubleshoot it in that state since we were down so 
I had to disable the session ASAP. Once the RFO comes in, I'll be 
asking a lot more questions about it. My only experience with BGP is 
as a customer so I'm not too familiar with the intricacies on the 
provider side. We had an outage in the AM the same day and we failed 
over just fine. I'm very curious why the same didn't happen in the evening.

Did you verify your problem was announcements on the other side of the
outage?   This sounds to me like you are using a bgp announced default
route from cogent which is always sent.    I think the problem was you
were sending traffic out a path that was broken.   Since you mentioned
your outbound balancing this would explain some packet loss and not 
100% loss.
