wordpress This webpage is not available

I was able to access my site sploat without problem just a couple of hours ago. But now my site doesnt load. My browser gives the following message

This webpage is not available
The connection to www.sploat.com was interrupted.
Here are some suggestions:
Reload this webpage later.
Check your Internet connection. Restart any router, modem, or other network devices you may be using.
Add Google Chrome as a permitted program in your firewall's or antivirus software's settings. If it is already a permitted program, try deleting it from the list of permitted programs and adding it again.
If you use a proxy server, check your proxy settings or contact your network administrator to make sure the proxy server is working. If you don't believe you should be using a proxy server, adjust your proxy settings: Go to the wrench menu > Options > Under the Hood > Change proxy settings... > LAN Settings and deselect the "Use a proxy server for your LAN" checkbox.
Error 101 (net::ERR_CONNECTION_RESET): The connection was reset.

What should i do to recover my site ?
