There are some trustworthy business class web hosts
. We have only just touched the top of the iceberg on spotting a poor web host. Choosing a web host is very very difficult. If you are looking for a quality business class web host, then do your homework. Search for reviews, talk to existing customers. Google can dish the dirt brilliantly on a company. Look up the company and see what you find. Remember above all, to pay monthly for your hosting so it does go wrong, and if the nasty stuff does hit the wall make sure you get a backup. Good luck.
