This has been explained many times before. As typically downtime is limited to less than a day or so, we have not implemented such a thing. Also any downtime past 24 hours is immediately refunded to the key as soon as the bot goes up, so there is zero loss. The next best thing would be a suggestion sent in regarding the status of the PF servers Greenlight for online and Redlight for down for maintenance, however there is no guarantee that this will be implemented, I can at least forward that on to the higher ups for consideration.
