The Ofcom report on UK Broadband says 97% of 1,500 residential connections in May 2010 (18 million tests) received speeds lower than what was advertised to them.

We found that average download speeds remain well below the speeds which some ISPs continue to advertise: the average download speed received in May 2009 of 5.2Mbit/s compares to an average headline speed of 11.5Mbit/s, equivalent to 46% of the headline speed.

65% of the UK is said to have broadband at home. Perhaps the most important statistic for security research is this one:

It is estimated that around 2.75 million households, are currently incapable of receiving a minimum speed of 2Mbit/s which the Government has targeted as part of its universal service commitment.

This compares to 40% of American homes have no broadband and 30% have no Internet access at all.

Germany and Greece have the highest penetration increase rate (3%), according to the OECD, while Korea (94.3%) and Iceland (83.2%) have the highest percentage already connected.

These numbers beg several questions related to the economics of threats, especially in terms of bot-infected computers.
