I have been in touch with webhosts - 1%1 and they have admitted the problem is theirs! Within a few minutes the problem was rectified. I will contact the "head shed" on Monday to request some money back or a period of free hosting. This has caused us to lose many hundreds of potential visitors and we are not at all happy...
We welcome and comments or suggestions from users out there.
Sorry for you have experienced these access problems....
