#1 Dreamhost: Dreamhost prides themselves on keeping up to date with the latest framework updates. In short, Dreamhost stands ready to rock and roll. When questioned about how soon they will be moving to Rails 3.1 after its release date they responded with “we will when it’s released, but only after our admins test it”. Which should be comforting, considering you want the techs from your hosting provider to be up to date as well. ;)
#2 HostGator: HostGator keeps its servers up to date with the most recent software upgrades. When reached for comment they responded much the same as Dreamhost. “We try to upgrade our software as often as we can, but we will only upgrade when we are 100% sure the software is completely stable and compatible with our servers.” Again, testing is a good thing, due to the fact that your hosting company needs to be as understanding of the software they support as you are, if not more.
#3 LiquidWeb: Liquid web allows you to install anything Linux compatible on their dedicated servers with full root support. When contacted they stated “on dedicated servers you can install anything linux compatible” “we can also install it for you”.LiquidWeb offers fully managed Rails updates on VPS, shared, and dedicated servers, ensuring you will always be using the most up to date and secure software available.
So what’s the deal with the vast majority of hosts maintaining support that isn’t up to date? The answer is possibly laziness, and possibly due to the cost and effort required to actually keep up to date with software and support for and ever growing Rails community. I would say it’s a lack of commitment overall that leads back to something I talked about in my article "Rubyphobic? Why some web hosts hide Ruby while others feature it.". The majority of hosts are afraid to take the steps necessary to become a fully committed Ruby on Rails host, sad really.
