Britain's Broadband Speed Map

The Financial Times has mapped the average broadband speed in every postcode area in Great Britain. Surprisingly the map reveals that the inner cities often have the worst broadband speeds.

You can enter your postcode into the FT's Broadband Speed Map to see the average broadband speed in your area and how that compares to the national averages. The red areas on the map are the areas with the slowest average download speeds and the yellow areas have the fastest download speeds.

As well as the interactive map the FT article includes a small multiple map visualization showing the average download speeds in nine of Britain's largest cities. These maps show that city centers often have slower internet speeds than city suburbs and many rural communities. The FT explains that one reason for this is that most recent investment has been into installing ultrafast broadband networks in the suburbs. While rural and inner-city areas have been left behind.
