What ISP are you with and are you satisfied with their services? I'm with Virgin Media and I have to say that I hardly get many problems. Out of a month I would think that my broadband is up around 98% of the time and it will depend from month to month. I did have a problem where it went down three times in one week for a few hours at a time but that's never happened before and not since. I wouldn't change unless there were drastic changes to my service.
