Does anyone have any idea why all the r3 spot instances have jumped so much in price over the last week? I understand that it's a market place and the price is just driven by demand / availability, but it's gone "rather wonky".For example, the r3.8xlarge instances are normally around the $0.28 mark, with the on-demand instances being $2.80, so why are people paying up to $20 per hour?
