A website which is down can be caused by a few issues.
1. Server is down
2. Your IP might be blocked by our firewalls
3. Connection issues
To diagnose the fault, please first go to http://www.downforeveryoneorjustme.com/ and put in your domain. This website will tell you if your website is actually down, or not.
Open a ticket for support after doing that and let us know the result.
