Our DNS provider, Zerigo is currently experiencing a DDOS (Distributed Denial of Service) Attack which is causing WPEngine.com, the my.wpengine.com portal and many customer sites to not resolve.
We apologize for the inconvenience, we are investigating backup solutions while also waiting on Zerigo to implement a fix for their attack.
We will keep you informed of developments and you may also monitor http://zerigostatus.com/ and https://twitter.com/zerigo directly.
