I once had a legitimate difficulty and posted to this list as a direct result. As I was moderated at the time, my post was denied with the provided reason that it was not appropriate for this list. An attempt to identify the source ISP of a troublesome IP was not "appropriate" but the below (and etc.) is? Still, still, exercising undue discipline - unlike others. -- Scott Berkman wrote: > , drop, and roll? > > -----Original Message----- > From: Aaron Imbrock [mailto:aimbrock@gmail.com] > Sent: Monday, January 12, 2009 1:12 AM > To: NANOG(a)nanog.org > Subject: > > Stop >

What to do when your ISP off-shores tech support
by Matthew Black 11 Jan '09

11 Jan '09

I've had difficulties reaching anyone with a brain at my DSL provider Verizon California. I can reliably ping the first hop from my home to the CO with a 25ms delay. But if I ping any other location, packets get dropped or significantly delayed. To me, this sounds like Verizon has an internal routing problem rather than a problem with my phone line. Note that it rained recently in our area and the cable vault in front of my is usually covered with stagnant water because the gutters don't drain it away. I have tried to explain this to tech support but they refuse to go off script, even the supervisors. They keep insisting on sending a tech to my home when I suggest this should be escalated to their network operations team. Anyhow, if I can reliably ping the first hop from my home, would that eliminate my telephone connection as part of the problem? Just a sanity check on my part. Thanks. matthew black california state university, long beach

XO -- Plea for engineer to contact me
by Owen DeLong 10 Jan '09

10 Jan '09

I apologize to the list, but, I'm at my wits end. Can an engineer with clue PLEASE contact me regarding ticket 1781923. I cannot get past the phone operators to speak to an engineer about a misconfiguration on the XO side with my service. I don't know what's actually in the ticket, but, I'm not requesting a major configuration change. The BGP session _IS_ working, except XO is failing to accept a single prefix from us which XO assigned to us. The response I'm getting from customer care is not matching these facts. Thank you, Owen

ebay dropping asymmetric traffic?
by Jack Bates 09 Jan '09

09 Jan '09

Ever notice you can't reach routing peeps by phone anymore? I have a few networks which are routing out one provider and return another. Not general practice, but it's ended up that way. As of last night I've had reports flowing in of these networks unable to hit ebay. The other networks in that area which leave and return via the same route seem to be working, and the broken networks returned to operation status when we forced ebay traffic around the network to make the flows symmetrical. I've heard this is causing problems in other networks as well. Has anyone seen this? Any idea of the specifics? I'm almost tempted to believe it's some form of RPF on inbound traffic (the observed path was via their cox interconnect). Jack
