Ofcom have just published a report on fixed line broadband speeds for each area of the UK. The figures shows that 60% of people on Anglesey have broadband. The average speed is 5.4 Mbit/s. From my own experience this must relate to the large towns as most people I know have a lot less!
Ofcom figures suggest 22% of the population are currently on less than 2 Mbit/s while 0% have superfast broadband.
