“This site cannot be accessed”

I recently moved to my own hosted site and at first I sometimes saw this error, but since yesterday its been on all day and Jetpack is not working. Any idea?

“This site cannot be accessed”.

Can anybody help me resolve this?

Based on older threads I checked the xmlrpc.php and it looks fine:
http://www.electric-rain.net/xmlrpc.php

~ % curl -A “Jetpack by WordPress.com” -d “<methodCall><methodName>demo.sayHello</methodName></methodCall>” http://www.electric-rain.net/xmlrpc.php
<?xml version=”1.0″ encoding=”UTF-8″?>
<methodResponse>
<params>
<param>
<value>
<string>Hello!</string>
</value>
</param>
</params>
</methodResponse>

Thanks in advance.
