Personally, I would have preferred that the caution showed itself prior to rolling out something that doesnt support ICMP sufficiently. Caution at that stage would have been most appropriate and most welcome. :-) Can you elaborate on which vendor and what specific issue you are dealing with? That might alleviate some head scratching as we (any affected parties) all await the vendor fix. I've got an HTTPS application that used to work great when InterNAP was giving us a path from Dallas to Atlanta over UUNET's network. But when we moved to Plano, InterNAP started pushing us over AT&T. The RTT is fantastic to our destination which is why I suppose we have that route but I suspect that it's not simply ICMP that's getting dropped on AT&T's network. Sorry, I've heard it from mutliple sources that it's just ICMP that's getting deprioritized/dropped but I'm skeptical. I've lost a little faith in the InterNAP secret sauce. :( -----Original Message----- From: Truman, Michelle, SALES [mailto:[email protected]] Sent: Friday, March 21, 2003 2:01 AM To: Mohammed Al Sukkar Cc: [email protected] Subject: RE: Problems with AT&T Mohammed, AT&T is working with the vendor on a fix. It has to be compatible with all other protocols and services running in this network. This is not a small network and so these things take a bit of time. It will be done, but perhaps not fast enough for you. There's certainly no telling whether the other carrier you reference is using the exact same platform as AT&T, or services. We're cautious about these things.
