Survey on Internet Disputes.
Hi, I am Kshitiz Verma, a Ph.D. student in Madrid, Spain, working in the area of studies on the Internet ecosystem. We are conducting a survey on the Internet disputes, not limited to, but mainly focusing on de-peering. We will appreciate responses from the community that help us build our data on such incidences. We did an initial search ( https://docs.google.com/spreadsheet/ccc?key=0Ajn7QWBNzSlLdGo3UzFDVkNvdGVwYncxNUdJclZWcnc&usp=sharing#gid=0), but unfortunately the results we obtained were mostly limited to well known disputes in North America. We believe there should be more of them but are hard to find, 1. if they occur outside the Tier 1 regime. 2. if outside USA. 3. because the local news may not always be in English. 4. they may not last long or may not have as big an impact and find place in news. We are posting We are also looking for instances like Youtube hijacking by Pakistan Telecom is not a dispute between any two ASes but still for repairing purposes, connectivity between Pakistan Telecom and PCCW (AS 3491), Hong Kong was disrupted. At the same time, we are not looking for disruption of the Internet connectivity due to an accident like Taiwan earthquake in December 2006. As claimed in http://www.cs.columbia.edu/~misra/news/CD070113.pdf , 500 to 1000 de-peering happens on a daily basis today. We are curious to know how this number has evolved since its inception (starting from post commercialization of NSFNET is already very good but before that is excellent :-) ). Please fill in the following form if you have some information that you may want to share with us. Also, as there are so many de-peerings happening, there is a high possibility that most of these don't become International News, so to get information on these disputes we expanded our search to local and regional News but unfortunately this has not added significant information. Once the results are processed and filtered, we intend to share them publicly. Form: https://docs.google.com/forms/d/1X6msZeK0_3SIaIK8IxZaO2-Vrl1MPh_8dTSpbG0oGzY... Many thanks in advance :-) Kshitiz Verma

I suppose this is just by technical incapabilities. People leak prefixes, hit max-pref limters, forget to clear sessions or don't bother increasing limits, they migrate gear from Cisco to Brocade or Juniper and cannot recover encrypted MD5 passwords... or management decisions decide to pull from an exchange. I don't consider this "de-peering" a peering dispute or an offensive act. The majority of vanished BGP adjacencies are due to laziness or technical limitations. -- Fredy Kuenzler Init7 (Switzerland) Ltd.

Thanks for the clarification on the number. I was surprised to see that number too! At the same time, we couldn't even find genuine disputes apart from the ones we shared. It seems there should be more but we just could not find them on the web. On Mon, Mar 24, 2014 at 2:53 PM, Fredy Kuenzler <kuenzler@init7.net> wrote:

Much more common than actual depeering is the passive-agressive version, where you continue to peer but bring a smaller hose to the peering point than the peering partner does. We see a *lot* of reports of the resulting congestion and packet misbehavior on this list...
