The reliability of your hosting will be excellent for any package, and if you choose one of their redundant cloud services it is even better.  The company says they are developing fail-over IPs and also offer load balancing, which will further improve the stability of the company.  Some of the features will depend on which data center you have your site housed in, but they are all quite good.  The bottom line here is that you won't have any trouble in terms of outages with this company.

As you look through the different sections and services on the OVH website you will quickly see that they have a lot of features available.  First, their shared hosting service offers three different packages, each of which are designed to meet small or maybe mid sized websites.  They are reasonable in terms of disk space, bandwidth and more.

If you have a larger site or get more traffic, you'll want to move to their VPS services.  They do offer VPS servers that have solid state drives, which can help improve the overall speed of your website.  This company offers cloud services along with their VPS hosting, which will allow you to further increase the uptime for your websites.

The dedicated servers start at pretty low level and move up from there.  This gives you plenty of options to ensure you're getting the power you need without overpaying for something you don't.  Their dedicated servers can also come with cloud technology to help improve reliability and speed.  You can choose to have the dedicated servers housed in a variety of data centers to ensure it is close to your customers.

The tech support with this company is very responsive and they really know what they are doing.  Given how many sites and other equipment they support it is no surprise that they do such a good job.  There have been some people I found who complained about not getting the help they needed when they submitted a ticket.  Given the size of the company, however, it is easy to see how things can fall through the cracks occasionally. They also have pages for showing the status of their network, servers and data centers, which is very nice.

The prices vary significantly based on the packages you choose.  You can, for example, get a SSD VPS hosting package starting at just $3.49 per month.  This is a great price, and while you won't be getting too much hard disk space or other features, it does give you the control of a VPS.  Even with cloud hosting options it starts at just $8.99, which is a great deal.  Once you move past the initial hosting packages, the prices do go up significantly.  You do, however, get what you pay for.
