The Internet is, by very definition, an interconnected network of networks. The resilience of the way in which the interconnection system works is fundamental to the resilience of the Internet. Thus far the Internet has coped well with disasters such as 9/11 and Hurricane Katrina – which have had very significant local impact, but the global Internet has scarcely been affected. Assorted technical problems in the interconnection system have caused a few hours of disruption but no long term effects.
The report was written by Chris Hall, with the assistance of Ross Anderson and Richard Clayton at Cambridge and Panagiotis Trimintzios and Evangelos Ouzounis at ENISA.
