The apaches::monitoring class uses check_http_wikipedia which in turn use the hardcoded en.wikipedia.org URL. The end result is a 403 forbidden error since that virtual host is not available in beta.
Example of output from bot:
PROBLEM HTTP is now: WARNING on deployment-apache23 i-00000270 output: HTTP WARNING: HTTP/1.1 403 Forbidden - 366 bytes in 0.006 second response time
We need to alter apaches::monitoring to use a different monitor service for deployment-prep project, aka check_http_url.
