Latency between Global Crossing & AT&T
Has anyone noticed excessively high latency between Global Crossing and AT&T? From what I've gathered, the PNIs between Global Crossing and AT&T are completely maxed out. The word is AT&T will not increase peering capacity with Global Crossing since their in bankruptcy protection. I am certain that this is affecting a large number of both Global Crossing and AT&T customers. I think it's fair to say that both Global Crossing and AT&T are amongst the larger Tier 1 providers out there, it's shameful that they can't come to an agreement on upgrading capacity. bash-2.05a$ traceroute www.att.net traceroute to www.att.net (204.127.166.135), 64 hops max, 40 byte packets [..] 4 0.so-0-2-0.gbr2.nwr.nac.net (209.123.11.234) 1.991 ms 2.254 ms 1.908 ms 5 5.ge-0-0-0.gbr1.nwr.nac.net (209.123.11.221) 2.063 ms 10.506 ms 2.075 ms 6 so-0-2-1.ar1.JFK1.gblx.net (64.211.83.61) 2.576 ms 2.704 ms 4.343 ms 7 pos3-0-2488M.cr2.JFK1.gblx.net (67.17.72.17) 2.564 ms 2.577 ms 2.125 ms 8 pos0-0-2488M.cr2.NYC1.gblx.net (67.17.64.138) 2.681 ms 2.698 ms 2.270 ms 9 so6-0-0-2488M.ar2.NYC1.gblx.net (67.17.64.158) 2.760 ms 2.724 ms 2.748 ms 10 208.51.134.6 (208.51.134.6) 144.483 ms 146.267 ms 143.238 ms 11 tbr1-p011601.n54ny.ip.att.net (12.123.1.122) 148.627 ms 153.665 ms 150.902 ms 12 tbr1-cl1.cgcil.ip.att.net (12.122.10.2) 171.625 ms 175.044 ms 170.965 ms 13 tbr2-p012501.cgcil.ip.att.net (12.122.9.134) 175.628 ms 172.361 ms 174.355 ms 14 tbr2-cl7.sl9mo.ip.att.net (12.122.10.46) 179.093 ms^C regards, /sjs -- Steven J.

A little poking around in the att/gblx route servers shows that capacity issues in NYC/WDC are in the GBLX->ATT direction, FWIW..

According to Global Crossing, the NYC peer is maxed during peak periods, and AT&T is refusing to increase capacity. No ETA at this time regarding a resolution to the problem, which is most certainly a business issue, not a technical one. -- Drew Linsalata The Gotham Bus Company, Inc.

<snip> I've seen the same, and was given the same reason on the GBLX->ATT peer in SFO. It was intermittent, happening on a daily basis, over a month ago. I've since prepended 7018 routes received through 3549 quasi-permanently. Grant -- Grant A. Kirkwood - grant(at)tnarg.org Fingerprint = D337 48C4 4D00 232D 3444 1D5D 27F6 055A BF0C 4AED
