I have been using Liquidsix for approximately 8 years now, and I have always been delighted by the service they offer. I have had the same reseller account for all this time, sitting on a windows server. I have had sites running OsCommerce, Joomla, ZenCart and Prestashop with no issues. They are very responsive in terms of issues, I once had a web hacked (due to my own fault for not keeping OsCommerce up to date) and they helped me isolate the incident and restore the site. I have used six or seven different hosting companies in my digital life, and LiquidSix is by far the best of all of them in my opinion.
