[AG-DEV] ANL Bridge registry turned off ?

Mon Jun 11 22:31:11 CDT 2012

Hello team,

After a purge yesterday I had 24 bridges, and today a purge gives me 19.  That's plenty!  Auckland and a few Oz bridges at the top of the list.

Shouldn't need to. However if you're asking because you're not seeing bridges now after a purge, its because the registry itself isn't running  for some reason. I'm looking at it now - actually, immediately after an appointment I have right now ...
