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.
