We were seeing issues here as well, we have BGP to Level 3 down until they stabilize. We were seeing a number of sites as unreachable, but ping tests from the Level3 IP address on that interface were working. Looks like perhaps they stopped advertising our addresses or were advertising them through an incorrect path. -----Original Message----- From: David Hubbard [mailto:dhubbard@dino.hostasaurus.com] Sent: Monday, August 01, 2011 1:43 PM To: nanog@nanog.org Subject: RE: L3 Issues Seeing a big drop in outbound traffic on our L3 link starting about that time (we're a web host). Getting calls about sites down too; all the traces I've walked customers through so far have died on L3 networks. David

Hello and Good Morning,

Are there reports of L3 having issues this morning ? Starting at about 10:10 A Pacific, I started seeing huge drops in traffic at various sites, including San Diego, Houston, San Antonio, Charlotte, NC, Philadelphia, etc. Anyone seeing a similar behavior ?
