Internal server errors on box75

[squash]

I am getting this since 10:30 AM CST for all my domains. I did a live chat and they said there was a problem with that server which the admin is working on to correct. Any idea what the problem could be? it's been down like this for nearly 4 hours now..

Apparently enabling the fast-cgi broke all my php pages? So I disable it , and it works? That is very strange since I had it enable for a few weeks with no problem, then all of a sudden all my php files broke, even really simple ones?
