The apache2 is disabled per the puppet manifest. Whenever our apache boxes reboot, they end up not listening to HTTP traffic. This is caused by the puppet production lass which exec mw-sync before starting the apache2 service. That is done in production to ensure we do not add in the pool an out of sync apache.
We have to manually restart apache2 on all apaches:
sudo service apache2 start
