A neighbour of mine was with 'Talk Talk' and, a few years back, when severe lightening struck in our area and all telephone lines were put out of action, he was last on the list for attention by BT whose landlines were involved with the service he was getting from TT.
It was a severe thunder storm and lightening actually struck my house and my Insurance claim involved the 'write-off' of a 'plugged-in' Laptop, Desktop, TV set, Bedside Radio etc. However within 24hrs I was back on line Telephone wise and, if my comps had not been put out of action, I would have been back on line for the Internet.
Good on BT I say......Ron.
