Lloyd,
I think there's some sort of timeout or ageing mechanism such that if
you did a purge before removing www.accessgrid.org/... and then
another purge, the list of bridges will remain the same as before. I
think if you were to wait 5 (or 10, or 15, whatever ....), another
purge would produce fewer bridges. Also, I think you'll need to Save
after deletions to the peers.txt entries.

Yes we've found that too. As soon as you do a purge on that machine,
it will look through the bridge registries for bridges to test and add
to the list of bridges - also removing bridges not registered with
whatever registries you have enabled (bearing in mind the ageing
mechanism for remembering them).

Most of the previous bridges are still running and will work if their
existence is still recognised e.g. by unpurged VenueCLients. I think
they probably need to be restarted so that they're registered with the
new registry. Do you know who runs that bridge to ask them to restart
it?
