Windows updates represent about 3.3 per cent of all bandwidth used, Yimg (Yahoo!'s image server) 2.7 per cent of all bandwidth used and Google – 2.5 per cent of all bandwidth used.
When looking at traffic, rather than bandwidth consumption, Facebook is the top site visited on business networks. Network Box's analysis of 13 billion universal resource locators used by businesses in the first quarter of 2010 shows that 6.8 per cent of all business internet traffic goes to Facebook, an increase of one per cent since the last quarter of 2009.
Google vists represent 3.4 per cent of all traffic, Yimg (Yahoo!'s image server) 2.8 per cent of all traffic, Yahoo 2.4 per cent of all traffic and Doubleclick about1.7 per cent of all traffic.
The company also found that, of 250 IT managers surveyed about their biggest security concerns over the coming year, the top concern was "employees using applications on social networks" while at work, with 43 per cent of respondents saying this is a major concern.
"The figures show that IT managers are right to be concerned about the amount of social network use at work," says Simon Heron, Network Box internet security analyst says.
Such measurements always are a bit imprecise, not in terms of URLs visited or bandwidth consumed, but in terms of business or personal use. Business users increasingly are using YouTube business videos for work, while some Facebook use undoubtedly also reflects business purposes.
