my pov after wasting money , time and effort for hosting from jw:
go to webhostingtalk and find those big boys company offshore if you want a stable host.
you want someone who dedicated, full time job as hosting to work for you, you dont want people who take hosting as their part time or dare i say "hobby"to host your site.
contact the provider and tell them what kind of website u are running (warez, adult, hacking, nulled script, w.e), by contacting them you have an idea of how fast their customer service is. i tried to submit severals ticket in different time, one in the morning like 10am and one like 2am to see how promptly they response, if they take half a day to answer my ticket then i would move on lol. i used wrzhost and webden if u care to know. longest time i got response from them was...well, couple days. you can see how pro they handle their business.
