MtGox Server Problems

I'm not sure what is causing this, but for the last months, the MtGox site has been showing up as:
This webpage is not available

The connection to was interrupted.
I assume there might be a problem with their htaccess configuration or the https certificate configuration. Anyways, it's not a serious problem since it usually works when reloading the site. This is the error message my browser reports:
Error 101 (net::ERR_CONNECTION_RESET): The connection was reset.
