SR.org lives on its own apache server to prevent it going down and taking out the rest of the projects VM. To fix it:
1. cat /var/run/srorgapache.pid for a PID File, and check that that pid is an apache2 file running with the srorg config (using grep). 2. Kill this process. 3. Run /etc/init.d/srorgapache start
This weird process is a side effect of how the srorgapache init.d script is written; because it is the same process name (apache2), the apache init script will kill the main projects VM if you just run restart.
The server runs on port 8090; it takes about one minute to become available after the server is started. You can access it directly at http://spatialreference.org:8090, and http://spatialreference.org is proxied through the main apache.
