That seems if anything with your ssl certs is broken...
if i look at
[Mon Jul 24 09:15:01 2006] [warn] pid file /root/ispconfig/httpd/logs/httpd.pid
overwritten -- Unclean shutdown of previous Apache run?
Would that time match the "network" crash of your provider? If yes, sure that it was only the network not the powerline? Maybe a power loss on your server caused a demage on your filesystem destroying any certs?
Or just take a look at you uptime to see if your server was rebooted withoud you knowledge...
