RE: Cogent Router dropping packets
Same here... frequent packet loss. We had Cogent GigE service for about 9 months if I recall - more than one major outage per month and packet loss issues at least once a week.

RE: RIR filtering Level3

Naturally. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Justin Shore Sent: Wednesday, November 14, 2007 9:43 PM To: nanog@merit.edu Subject: RIR filtering Level3 Are any other L3 customers seeing the large number of /25 and smaller routes from L3? I'm seeing almost 2500 of these routes in 4/8, some but not as many in 8/8 and still more in L3's non-US allocations. Looking at the AS paths for a handful of those specific networks I only see them via our L3 connection and not via our other 2 upstreams. I'm seeing paths to the larger aggregate networks via our other upstreams of course; the Oregon and ATT route servers see the same aggregates too. To be more accurate we actually touch L3's acquisition form a year or so ago, Telcove (19094). All of the small routes are originating from L3 though (3356). Best I can tell L3 is aggregating before it advertises to a peer but not before it advertises to a customer. Or, on the otherhand, perhaps L3 is advertising without aggregation to Telcove and Telcove is not aggregating before advertising to us. So, that said, what is everyone else doing to perform sanity checks on their learned routes? Are a good many implementing RIR filtering and dropping everything smaller than a /24? L3 of course isn't the only source of these tiny routes but it's so obvious I saw it and wasn't even looking for it. This would explain why I'm getting so many more routes from L3 too. I'm getting 232k from ATT, 233.5k from Cox and 244k from L3.

RE: Least Sucky Backbone Provider
We had the same issues with Cogent .. I feel your pain... level(3) has always been good for us - very few issues and their support has been great from our perspective. MCI/Verizon did not work well for us at all - their network was solid and customer service wasn't too bad ... our problem was that less than 20% of our traffic was preferred via MCI's routes. Funny how one of the largest networks in the world was the least attractive BGP wise of course everyone's network is different with every provider so YMMV Never dealt with ATT as we're based in Canada...;) Paul -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Gregory Boehnlein Sent: Monday, November 05, 2007 10:52 AM To: nanog@merit.edu Subject: Least Sucky Backbone Provider Good morning, I'm considering dropping Cogent completely out of my transit mix, as the number of outages and problems they have been experienced over the past year has reached an unacceptable level. It has gotten to the point that we their BGP session is shutdown for longer periods than it is on. Based on the availability of on-net fiber in my facility, I have narrowed the field to the following candidates: 1. Level 3 2. MCI/Verizon 3. ATT I'm looking for comments from actual customers of the above providers in relation to; 1. Network reliability and performance 2. Responsiveness to outages 3. Proactive notification of network maintenance 95% of our traffic mix is US48 in nature, so International routes are not a huge decision point.
