London is the biggest international hub city on the internet, according to a report by research company Telegeography, which also said international internet traffic is growing faster in Latin America than in any other region.

There is 1.1Tbps (terabits per second) of international internet bandwidth available on connections terminating in London, and peak traffic in and out of the city is about 439Gbps, according to Telegeography, which on Wednesday released a report entitled Global Internet Geography.

The report reflects only international capacity and traffic and excludes domestic statistics. Telegeography, based in Washington, DC, is a division of PriMetrica.

The US has the most international bandwidth of any country, at 1.4Tbps, about 704Gbps of which is being used at peak times. This reflects not just the large number of users and high-speed connections in the country but also international traffic that goes through, said Alan Mauldin, a senior research analyst at Telegeography.

However, peer-to-peer filesharing takes up a lot of international bandwidth: some internet service providers (ISPs) told Telegeography it makes up 60 per cent of their traffic, Mauldin said. Because peer-to-peer applications deliver content from all over the internet, consumers may not be aware they are crossing borders to download it, Mauldin said.
