not horrible. but not the greatestIf the network is horrible there's no reason to spend money on a system like that.
Source: Paid 30/month for a Dual L5420 with 16GB RAM and 2x 1TB HDDs on a 100mbps port.
The network was so bad it took me 400ms+ for it to get to me (when I was in Central PA). This was still in the States... single homed with Quest. I think most of you know who it was. (since then they upped the price to 90/month). Others had better experiences with this company but mine have been horrible.
