I loved Siteground at the beginning, and would be the first to recommend them. I stayed with SiteGround through price increases because of their amazing customer service. They helped with any issue and if I had a problem, I knew I wouldn't have to worry.
Now, their live chat feature can be turned on and off for users at their whim depending on past questions or issues. Recently, when my sites went down, I could not contact any one immediately because they had decided live chat was unavailable for me at that time.
My sites have gotten progressively slower even though I've upgraded service, and I encounter 503 service unavailable errors constantly. These errors pop up so much now that is affecting my sites' SEO.
They're just gotten rid of the Cpanel, and their Site Tools is now limited. I was not made aware that there would be changes with the SSL settings once Cpanel switched to their in-house site tools. Now all of the sites are experiencing SSL issues.
Will be switching at the end of this month because I don't believe the service is worth the price anymore. Review collected by and hosted on G2.com.
