I guess they may not be. Makes it a pretty murky system then. Amazon know what our max bids are and they're adjusting the price. They obviously control supply, and that's dictated by on-demand usage, but the price itself must surely be the lowest bid out of all those that still have a machine. In terms of the stability - it's generally really solid. You sometimes get spikes, but I've never seen anythingike this (and it's been going on for a few day). To give you an indication I had a box that was shutdown that had been running for about 1.5 years.
