Quest/Cerf peering

Anybody seeing a problem with Quest/Cerfnet Peering? I can't hit some servers that are colo'd at Quest when the routes pass through Cerfnet? Routes die at what seems to be the quest/cerf peering router. (I thought of the fact that they don't allow traceroute, and web and dns won't get through either). Don't see any problems when going through CWI or UUNet. Jeff -- Jeffrey Meltzer meltzer@villageworld.com Sr. Network Administrator http://www.meltzer.org VillageWorld.com, Inc. (631) 218-9090
