When we started offering colocation services we thought we’d try a new way of pricing them per PSU watt rather than a fixed price for space. This way our customers would be rewarded with lower pricing for choosing green equipment that uses less power, and their price would be fairly based on the resourced they used. However, this turned out to be a bad idea because either it was too confusing or nobody believed we could offer service for the prices we were quoting.
As such, we have decided to eliminate the per PSU watt pricing and use traditional pricing for shared space 1U and 2U servers with a high capacity power option. Quotes using the old method will still be honored until they expire. If the colocation industry ever changes in such a way that customers are looking to save costs by using less power, we may decide to bring it back.
