There is a major power issue at the Datacenter affecting most of our equipment. Miraculously, our server is not one of them. Unfortunately, our resolvers are down which is why e-mail is unable to leave the server (working on that).
Colo4 is aware of the situation and is working to restore power to everything as soon as possible. Unfortunately they are unable to provide an ETA, but as you can imagine, it will be back as soon as it is humanly possible.
Problem has been fixed now. It was something that affected millions of sites.
Our apologies for the fuss,
ZE Administration
