It depends on where in some cases. Take Greenland for example. Prior to Tele Greenland possibly completing the Greenland Connect cable[1] real soon now (Halifax to Nuuk, Nuuk to Iceland, branched to Qaqortoq, with xcon to UK and Denmark) I seem to recall that a large amount of their capacity was via satellite from Godthab(Nuuk) to Denmark. In this case, you're likely talking 100%. Almost all of your remote cases are going to be in a similiar situation ie. Svarlsbad, most stuff above t~N60^ parallel (or so) etc. [1] Tele Greenland IT News Item (see last paragraph, Brian Buus Pedersen is Tele's CEO) Best, Martin Hannigan -- Martin Hannigan http://www.verneglobal.com/ Senior Director e: hannigan@verneglobal.com Verne Global Datacenters c: +16178216079 Keflavik, Iceland f: +16172347098 ________________________________________ From: Kevin.Smith@dca.state.fl.us [Kevin.Smith@dca.state.fl.us] Sent: Tuesday, January 06, 2009 15:34 To: nanog@nanog.org Subject: Estimate of satellite vs. Land-based traffic All, Participting in a severe solar event EXERCISE. Can anyone give me an educated guesstimate of the percentage of backbone traffic that is satellite dependent vs. that which is totally land-based?
