Swindon is top of the UK broadband league again, but is being "pushed hard" by Milton Keynes.
Point Topic's latest analysis found that 65.3 per cent of households in Swindon had a broadband connection, up 5.5 per cent from the end of June 2006.
But this lead now looks "shaky" as Milton Keynes climbed from 62nd to second place in just six months, displacing Cardiff as runners up, and increasing by 15.4 per cent to 63.7 per cent of households.
Cardiff, now in third, has 62.4 per cent household penetration. The UK average is just under 46 per cent.
"The introduction of 'free' broadband offers, increasing uptake of bundled services and migration from dial-up to broadband have all contributed to the rise of Milton Keynes," said Dr Katja Mueller, research director at Point Topic.
Milton Keynes has suffered since it was founded with aluminium phone lines when copper prices were at a peak in 1967.
An unusual geography means that many broadband subscribers get more faults and have access to lower speeds than other parts of the UK.
But the good news is that this marks Milton Keynes out as an "ideal candidate " for the deployment of fibre, which offers speeds of up to 100Mbps, 50 times faster than most consumer broadband connections in the UK.
Other local authorities in the top 10 include Epsom and Ewell, St Albans, Stevenage and Watford.
At the other end of the table, typically with less than a third of households on broadband, are West Dunbartonshire, Oswestry, the East Riding of Yorkshire and the Isle of Wight.
