What do you mean by ‘burst RAM’?

Ans: Bursting means that while you are always guaranteed a certain amount of system resources, far more is available on each box than simply these guarantees. Hence, should you require your loads to spike higher than your guarantees, as long as the resources are available on the box at that time, you can use them, up to your ‘burst’ level. We are constantly monitoring the loads of each server to make sure that nothing is oversold, and that customers always have their guaranteed resources.

We make sure that an ample amount of burst resources are always available on each host machine. Your burst allottment is not the same thing as your resource guarantee. You cannot count on constant, sustained utilization of your burst resources. If your VPS constantly requires greater resources than your package guarantees, we can work with you to quickly upgrade you to a package with greater guaranteed resources.
