It's pretty good. I am happy with it. There have been some niggling network troubles in the past leading to short periods of downtime, but lately it has been really good (no downtime) so I think they have managed to sort things out. DCJN is a lot better than the many other offers that seem to be popping up lately with cogent as primary and XYZ as secondary. You do get what you pay for. Also, like the full NAC network, DCJN uses the direct NAC pipe into the London Internet Exchange. That's what I like about DCJN, it might be cheaper and has less carriers, but you still get nice pings and short routes to the rest of the world, not just teh US.
