    Seems like your server was down for those 45 minutes. Try to restart your server:

    /etc/init.d/apache2 restart

    If the problem persists, try a full reboot.

    If the problem is gone, apache might have crashed - there was a bug in apache 2.2 (very old, resolved years ago https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=398223)

    If the problem persists, Do you have a system image from before the collapse? If so, comparison of configuration files may tell us if something was tempered with your server. If you have an SSH server there, check 

    /var/log/auth.log

    there may be other files:

    /var/log/auth.log.1
/var/log/auth.log.2.tgz etc

    find the one that contains the timeframe of interest and see for anything suspicious there.
