The ASF does not have offices or buildings, it's an intangible entity that exists only on the internet. Its only physical existence is the technical infrastructure that enables it to operate.
The ASF Infrastructure is primarily composed of the following services:
the web serving environment (web sites and wikis)
the code repositories
the mail management environment
the issue / bug tracking
the distribution mirroring system
The Infrastructure team is responsible for the management and day-to-day system administration and operation of the various hardware that runs the above services. They are also responsible for approving the installation of a new system or software on the ASF machines.
We deploy in production a number of Apache softwares, including HTTP Server (httpd), Subversion, SpamAssassin, Tomcat, Traffic Server, mod_perl, RAT (incubating), Gump and Continuum, Steve, mod_mbox, Pulse and Orthrus (see labs), Solr, Directory Studio, a selection of in-house projects (including the committers index and the committers URL Shortener), and the Apache CMS.
Below is a list of pointers to information on the services provided by Infrastructure:
