Need to switch Word Press hosts
I have a Word Press website for my business and am not happy with my current host. I am NOT wordpress savvy and regret having it built by them in Word Press. My current site went down for a couple of days recently and the host (its this guy in Nebraska who owns a hosting company and helped build the site) didn't even catch the site was down. I only caught it because a place I advertised at contacted me to tell me. Since then I have been using free Uptime Robot monitoring and in the last 30 days see it has been down 6 times "6 incidents, 24m, 37s down" It appears to happens in 4 minute episodes. My first question is
Is that normal for a site to be down that frequently?
If I switch to a host like Site Ground will I have to be tech savvy because I am not. I saw on the Site Grounds site I have to add code to even get automatic updates, I don't even know how to do that! Don't tell me I can figure it out either I am NOT a tech person at all so need to be sure my site will be okay if I switch from this guy to another host.
Also who uses Site Ground and would you recommend switching? And what other hosts might be good as well? Help!
