With multiple fingers in the pie, server configuration can become incredibly confusing. A great deal of time, research, and expertise has gone into the specific configuration of the hp.o server.
In order to prevent accidental or ignorant changes in the configuration (and to, hopefully, pass on some valuable knowledge), all configuration changes should be documented along with applicable references.
If the service you are changing is not mentioned here, please create a page for it!
Before making changes please consult the appropriate service's configuration page. Most often the default configuration file is not modified and instead individual override files are used. Each service should note this clearly at the beginning of their page.
