Why my server is up and down successively?

Question

Our server has just been hacked few days ago, we made a complete backup of it, but, from that time, we get erros while trying to access our websites hosted on it : some times, everything works perfectly, and then when we refresh the page, we get an error message :

Internal server error

Where could that come from ?

Thanks

You need to completely rebuild the server. See http://serverfault.com/questions/218005/my-servers-been-hacked-emergency. — Kyle Smith, Apr 05 '12 at 15:13
Please tell me you made a complete backup *before* you were hacked, because otherwise your backup cannot be trusted. — Jeff Welling, Apr 05 '12 at 16:26

Check the logs. The answer is there:

Apache Logs
Lighthttp logs: /var/log/lighttpd
Some nginx logs
Linux Logs:
- /var/log/message
- /var/log/auth.log
- /var/log/kern.log
- /var/log/secure
- /var/log/yum.log
MySQL logs: /var/log/mysqld.log
