I had some problems with them: SSRS (SQL Server Reporting Services) account expired several times and the reports stopped working and that is bad for business. SSRS is not a common need for websites but the point is how much can you trust them to support your client's business. Also I had some problems with server upgrades that did not keep compatible configurations. Also 2 years ago or so, support was much better.
