Does your provider replace your webpage content with: Bandwidth Limit Exceeded every once in a while?
In this day and age that should only happen, if your domain has a really big amount of traffic. Something in the order of tens of thousands of visitors daily. Even then you probably have your webpage configured poorly – pictures, etc too large.
Even then, it does seem as if North American hosting providers have not quite caught up with the Europeans. Most hosters there offer unlimited bandwidth and have for a few years now!
If you are faced with that problem, try contacting us at email@example.com and ask us about our hosting offers through European providers.
