I am sure I have talked about this subject before, but I fee like it is worth saying again.
If you are a professional web designer, or your choosing a host for your site for your site, pick a good web host. Places like Bluehost, iPage, Go Daddy, places like that. They offer reliable, fast servers that won’t fail on 99.9 times out of a hundred. There’s always a catch with a cheap web host and it’s usually speed and/or reliablity.
