The top nav tabs are oversized. Shrink them and add some white space in between.
On the hosting page, spread out the plans to the full width of the content area so that they are not so clustered together. If possible, break them apart with relevant imaging or organize them into a table for quick comparison.
The horzontal bars on the top and bottom should not expand with the page on higher resolutions, they just make the empty space more glaring. Either make the entire page fill the screen or make everything centered and the same width. For example: http://www.yahoo.com/
The rest of your site is great, especially the speed. Keep in mind however, that you have a lot of competition and should generally have one aspect about your hosting that can be considered the "best."
