More people who are struggling simply need to be made aware that they have choices and that a vastly better experience is available by changing to a good ISP like Zen or Andrews and Arnold. If a user needs more reliability, who doesn't, their are options such as FTTP (true fibre), Virgin's coaxial cable in towns and multiple lines (which is what I do).
Having multiple lines can make you relatively bomb proof at a certain level, against routine problems. Of course a digger may come along and knacker both lines together, there may be a problem in the exchange or there may be a problem further away in the BT or whoever's network from the exchange onwards.
My point is not that this is necessarily for you, but that everyone has these kind of options, for no extra cost or modest extra cost per month. An extra line costs me £12 per month.
