Like most web hosting companies, Site5 offers a full 99.9% uptime guarantee.  In addition, however, they guarantee that if your site goes down, they will refund you the money.  This is a nice little perk, though in most cases it is not something you will ever take advantage of (this is a good thing). In the event that you do run into trouble, Site5 has 24/7/365 live chat and email technical support.  They also offer phone support during normal business hours. There have been very few complaints about reliability from users of this company, and given the fact that they have so many different data centers, it is clear that they are able to provide exceptional reliability.

Be careful when you start browsing through their list of available services, it seems like it goes on forever.  Some of the more important options include unlimited disk space and bandwidth on all their packages (even the entry level ones).  All their packages also include free backups, a 99.9% uptime guarantee, easy website builder and much more. You can only have one website hosted on their lowest level package, but once you move up from that, they offer unlimited domain and website hosting. If you aren't 100% happy with the services you get from Site5, they offer a full 45 day money back guarantee, which will give you plenty of time to really evaluate their services properly.

Site5 offers a wide variety of differnet web hosting services to choose from.  Their entry level package starts at $4.95 per month, which is about average these days.  The prices go up based on the type of services you need. In addition to their popular shared hosting services, they also offer managed and unmanaged virtual servers, which are priced quite nicely.  For example, if you are a web expert and go with an unmanaged VPS, you can get a dual core, 1 gig of memory setup for just $25 per month.  It is $50 for the same setup under the managed option. It is important to note that their prices do change based on where you select to have your website hosted.  For example, a basic package in Dallas Texas starts at just $4.95 per month.  That same package is $5.95 in San Francisco, and $9.95 in Joao Pessoa, Brazil.  Make sure you are looking closely at where you want your site hosted.  It is often worth the extra money to get the location you want, but in some cases it is better to just go with the lower price.
