When you get say 1gig transit from HE do they dedicate 1 gig to you? Or is it a best effort?
Depends on how you look at it. All transit providers work on some form of oversubscription - it simply comes down to how much oversubscription and whether or not it effects your service. That's the biggest difference between "ultra cheap" and quality transit providers, besides routing quality, support, and uptime.
