I would have to guess here that you don't do backups on the server? Sorry, but this is no way to operate a mining pool or any other service/business, backups are critical and should be done constantly to prevent down time when you have people/users relying on the service. With a backup, it would probably have taken less than 2 hours to restore and your server is back up and in business.
There was no message about any issues and my miners were mining fine at 5:30 AM EST, I queued the requests to cash out my mined coins and it accepted, but now they are all showing pending status, and one is showing "0" pending which should be a couple 100 coins. I just hope all my mined coins are safe and will be transmitted once the system is back online and do not get lost because of this.
