Good deal, for Dell maybe
The problem GlassHouse have is that Dell are looking to acquire them cheaply. It's no secret that GlassHouse are suffering badly in the recession (hence the departure of Curtis Preston who was in many ways the face of the company) and the mainly US based investors want to see a return.
GlassHouse are also known to be struggling on the Managed Services front having recently had to let most of their UK based staff go.
