Upgrade vs. Free Account

I presently have a free account with a sub-domain. I recently experienced an outage, in which I could not my site due to a “502 Bad Gateway”. It turns out that other people experienced the same issue, which turned to be a server error. That being said, If I upgrade to the premium hosting can I avoid issues such as this in the future? I know that every server has its share of problems, but I run an online business and sell digital products. It is imperative that my sales pages have an up time of at least 99.9%. Will the premium hosting provide this type of service?

I don’t know, have you tried asking iFastNet about this?
