The government has replied to an online petition calling for an investigation into ISPs "throttling" bandwidth.
Customers had grown concerned that the ISPs were allowing too many subscribers on their networks, causing a restriction of speeds during peak periods.
The petition descried the state of broadband in the UK as "suffering" due to the supposed underestimation of customer usage.
In response to the charge that ISPs are tricking customers into paying for a service different from the one they receive, the government replied: there are a number of reasons why a subscriber may not receive the broadband connection speed advertised by ISPs.
Continuing: "One main reason is that for most broadband customers the maximum speed available declines the further they are from the telephone exchange."
The petition was believed to have been signed by over 2,600 people.
