The cause of this outage was a power outage that occurred due to maintenance of our datacenter, which knocked out A+B power at the same time for a short time.
Notifications about this maintenance were not sent out to us as they should have been by our datacenter due to an issue on their end.
We are still investigating the 47-DH-* rack. If your server is down, and on that rack, please reach out to us on https://get.crunchbits.com
