I have had a VPS with Digital Linx since December 4, 2008. I am more than happy with the service I have received from them. At first, their order and billing system was a bit wonky, but now it is working just fine. I have dealt with support a few times, and they have been very quick to respond. Their MSN support person is online a LOT. At one point, there was a heavy load on the VPS. I msg'd support on MSN and they were already dealing with it. It was fixed in 5 minutes. They were also quick to set up TAP/TUN, and were really good when I said I was going to set up the VNC I am currently running.
The only downtime I have had was when the entire Wholesale Internet routing to Cogent fiasco happened. That was not the fault of Digital Linx.
I currently do not have any website hosted on that VPS. I am using it as a VNC server/remote office. But, just so you know, I am posting from it
