I know there are a million ASP.NET hosting options, but what are the premium options if you have some money to spend and want maximum performance and uptime? We currently use MaximumASP and they are generally great. I know another good option is Rackspace. Does anyone have any other suggestions? This is one of those things that is hard to Google, because everyone calls their hosting option premium or professional.
I'd say Rackspace is a good choice, but I use discountasp.net because I needed .NET 3.5 SP1 hosting with SQL 2008 and they delivered.
The obvious choice would be to get a dedicated server, other than that I love: DiscountAsp.net as they always have the most up-to-date frameworks on their servers. Useful if your trying a new technology such as when MVC was in beta
I have used SoftSysHosting for a multitude of clients, and they have never let me down...plus, their Customer Support is excellent, accompanied with a Knowledge Base of FAQs.
I use ORCS Web for one of my sites. I've never had any problems with them in over 2 years. They asked me to fill in a survey a few months back asking what I thought of their support and I had to admit that I'd never really had to use them beyond the initial setup.
If you want something between shared hosting and Rackspace dedicated, check out their newly acquired cloud offering. I've been using it for a few months with a lot of success.
