Eleven2 promises a 99.9% uptime guarantee for all their hosting packages.  If the uptime drops below the 99.9% level, you will get a partial credit on your bill for the amount of time that your site is actually down.

There have been some customer complaints on their social media site.  They were mostly focused around periods of slow response and occasional downtime.  This was likely with their shared hosting options, though that was not specified.

Their reliability is even better due to the fact that they have data centers in Texas, North Carolina, London and Singapore.  These data centers are all staffed for quick response to any issues.

There are many different hosting packages to choose from, which each come with their own set of features.  For the most part all the features that are listed in these pacakges are fairly standard for the type of hosting.  One nice thing about this company is that you get to select which of their data centers you want to be housed in.  This is great for customers who are targeting a geographic area of the world, and want their site hosted near that.

All of the options they offer are run on Linux servers, which are set up well.  If you're looking for a Windows option the only choice you'll have is to get an unmanaged dedicated server, which would really not be worth it anyway.

Eleven2 offers 24/7 live support for all package levels which is very nice.  They do encourage you to use the helpdesk ticketing system when possible, but the live chat is also available.  They market the fact that they guarantee a response within 20 minutes to any tickets or other issues that are submitted.  They also have a phone line you can call in on, but that is not staffed 24 hours per day.

In addition to the technical support teams, they also offer a good knowledge base, video tutorials and much more to help you learn about your hosting and avoid problems on your own.

From top to bottom the prices from this company are all right in line with the industry standard.  There are some packages that may seem like they are over priced at first, especially with the dedicated servers.  When you look at the specs that you get, however, you will quickly see that the prices aren't out of line at all.

If you are looking for reseller hosting options, the pricing for this is quite good.  It will give you the opportunity to charge a fair price to your customers and still make a nice profit.
