These sites are fairly scattered and randomised, some are rural, others are town or city centre.
It is clear that on some sites, BT have intentionally avoided business parks (even when located near to dense residential areas) - I can only conclude this is to force businesses into buying leased lines.
Most of these sites are between 3 - 10 users and the cost of leased lines is too expensive, so they are forced to lumber on with totally inappropriate broadband performance.
I'd be interested if anyone has any links illustrating BT's commitments to SMB, Or if anyone knows of any community alliances or projects around small business broadband 'not spots' please let me know.
Personally, I think it's pretty disgusting that BT are allowed to force business onto leased lines in this way. They desperately need much tougher regulation and/or nationalising.
