i lost my broadband for well over a day so i contacted my isp (gio internet) who went through all the possible causes, after me telling him id checked everything he finally agreed that it was a loss of signal from the exchange and told me i should contact bt to have it resolved. I contacted BT and they told me that my line was fine several times even tho they couldnt check the line after much hullabaloo they still said my line was fine and that it was my modem that was to blame (quite how he knew this when he didnt even realise pci adsl modems existed i dont know). Miraculously my line got fixed shortly after. Point is, the bastards will never admit that its their fault and will always tell you its something that you have done.
