This code is part of Launchpad and not available. Even if it were I
don't think it would be the right solution. Here is how it works
Prober grabs the "manifest" file which lists the cd images and file
sizes for each.
Prober has a list of registered mirrors
Prober does a HEAD request for each cd image on each mirror.
If the file size reported by the http response header for the image
matches that in the manifest file the server is believed to have the
If the server has all of the images expected from the manifest file
the server is deemed to be active.
The Ubuntu site just grabs a list from launchpad of active mirrors a
