How to align DIV within Window - html

Question

http://jsfiddle.net/ApS9L
I have this DIV which I am trying to align with the other two divs. In the fiddle, you can see there is the border of 'our data center' and 'our other services', which align with each other in a 960 width frame (works great when resizing). However, I can't get the 'every account includes' to stay aligned with the two other sections below, and it stretches across, far beyond 960px.
Can you help me get the top div to align with the other two divs.
Here is an image of live to show you my issues (there is a another column but it was breaking the fiddle). The colums are all grid_4 so grid_4*3 = 12, which shouldn't be causing issues..
Here is FULL HTML, please look on fiddle for CSS

<div id="insidehostingservices" class="grid_12margin">
