I have a network (AS33234) I am trying to support that is downstream from Onvoy on one of their connections. Our monitoring equipment is located in AS4452. Our monitoring system is not able to ping their network through Onvoy. The block seems to be happening at either Global Crossings or Onvoy. We are able to reach them using any protocol other than an ICMP ping (We are able to traceroute). Does anyone else know about or see a similar block going on. I have attached part of a traceroute. 2 suwC6.gig3-1-4.qualitytech.com (216.154.207.145) [AS 20141] 0 msec 0 msec 4 msec 3 suw04-gig1-0-0.qualitytech.com (216.154.207.173) [AS 20141] 0 msec 0 msec 0 msec 4 gig6-2.suwangaeq01w.cr.deltacom.net (66.35.174.165) [AS 6983] 4 msec 0 msec 0 msec 5 * * * 6 pos5-0.atlngapk22w.cr.deltacom.net (66.35.174.101) [AS 6983] 0 msec 4 msec 0 msec 7 so-0-0-0.ar3.DAL1.gblx.net (64.208.169.141) [AS 3549] 4 msec 4 msec 4 msec 8 so1-0-0-622M.ar2.MIN1.gblx.net (67.17.71.34) [AS 3549] 44 msec 44 msec 44 msec 9 WBS-CONNECT-LLC-Minneapolis.ge-2-3-0.409.ar2.MIN1.gblx.net (64.215.81.82) [AS 3549] 44 msec 44 msec 44 msec 10 * * * 11 * * * 12 WikstromTel-7003.onvoy.net (137.192.32.30) [AS 5006] 52 msec 52 msec 56 msec -- Brian Raaen Network Engineer braaen@zcorum.com
