Mirrors list

[Timothy Hart]

Curious,

Is the list of mirrors fairly stable? I'm referring to the contents of the file at 

rsync.macports.org/release/tarballs/ports/_resources/port1.0/fetch/mirror_sites.tcl
and
rsync.macports.org/release/tarballs/ports/_resources/port1.0/fetch/archive_sites.tcl

I understand each port maintainer may change or modify their list of mirrors at any time. I'm interested in knowing how frequently that happens historically - and in aggregate.

Why?
I have an issue in my organization where our DNS servers are configured to 'helpfully' give an IP address back for every query. In cases where the host is actually not known, the IP address is configured to perform a search and respond with an HTML page. As a result macports installs can fail when the first mirror site is not found.

The network group is willing to consider white-listing macports mirror sites for us as a solution. I want to make sure that maintaining a whitelist of (currently over 300) mirrors won't turn into a maintenance headache.
