Level3 is having problems in SJC and ATL right now and they are definitely aware of it. Any packets that I send to them die at their ipcolo switch in those two markets. Level3 in LAX, DFW, CHI, DC, NYC, SEA, DEN all seem to be running fine. -Sean MegaPath Networks > -----Original Message----- > From: kwallace(a)pcconnection.com [mailto:kwallace@pcconnection.com] > Sent: Monday, February 23, 2004 2:53 PM > To: nanog(a)merit.edu > Subject: possible L3 issues > > > anyone else seeing high latency via L3 , especially the west coast ? > - Keith > >

L3 burp today - what happened?
by David G. Andersen 23 Feb '04

23 Feb '04

Anyone know what happened to L3 during the last hour? They seem to have developed an appetite for dropping packets in San Jose for customers on the Genuity portion of their network, but I'm curious if anyone has a slightly more detailed explanation about the failure. The failure seems to have started at 17:09 and ended at about 17:51 EST. -Dave -- work: dga(a)lcs.mit.edu me: dga(a)pobox.com MIT Laboratory for Computer Science http://www.angio.net/

Level3 issues?
by Scott Francis 23 Feb '04

23 Feb '04

one of my machines is at a colo facility that uses Level3 as a primary upstream, and I've been noticing significant packet loss off and on for the last hour or so. Heard from an Internap customer that L3 was having BGP issues ... anybody have more details? I haven't heard anything substantive. -- Scott Francis | darkuncle(at)darkuncle(dot)net | 0x5537F527 "I gave you the chance of aiding me willingly, but you have elected the way of pain!" -- Saruman, speaking for sysadmins everywhere

BGP, MED, Confederation presentation
by Sam Stickland 23 Feb '04

23 Feb '04

Hi, There was a link posted to this list about six months ago, of a presentation that showed how to use additive MEDs to set up traffic flows correctly between sites (where each site is it's own BGP confederation) and showing animation of the resulting (example) traffic flows. I remember that the technique it described was well regarded and that it was reasonably unqiue. Sorry for the vague description, but my web searches and trawls through the nanog archives have drawn a blank. I'm hoping that someone here knows what I'm talking about :) Sam
