In one of the two datacenters in the Netherlands we use (Easynet), The power feeds went offline. Apparently a Transformator failed. We are not certain why the emergency power did not take over the load. Our engineers are onsite and will check all affected servers once the power comes back online. Sadly our Email and website systems are both affected, we are working to bring at least Email system online asap.
Coming up for 7 hours is pretty extensive power related downtime. Thankfully only one of our servers is still down; however it's still a PITA. Hopefully the problem can be identified and preventative measures put in place going forward.
