The connection has timed out error with XenForo

Hey, my xenforo installation on InfinityFree was working until about half an hour ago when it said: The connection has timed out whenever i try to access http://modulplex.org/forum/index.php?portal. Does anyone know what to do? The main webpage http://modulplex.org works though.

Can anyone help?

Your site is working fine now. It’s probably still affected by the DDoS attacks hitting our systems and it took a while for the filters to fully kick in.

If this starts to happen more often, please let me know.
