All online & phone services for ending or transferring mobile contracts are of course overloaded and currently unavailable in France. FreeMobile's registration webpage (http://mobile.free.fr) has been unavailable for the past 5 hours. Figures fly on twitter, as apparently about 1.5 million people tried to access it this morning.
Streaming figures for the live keynote amount to 80Gb/seconds over 300 servers, Online.net representative @Online_fr said on twitter. Apparently 600,000 people watched the keynote live, Online.net even claimed it's a world record. (Online.net = Iliad/Free subsidiary dedicated to hosting services)
