[GitHub] [trafficcontrol] rawlinp edited a comment on issue #3687: Ignoring ADMIN_DOWN/PRE_PROD Cache Servers while setting parent_pending flag

   Currently, we check `ONLINE/REPORTED/ADMIN_DOWN` caches specifically and ignore all other statuses. I think including `ADMIN_DOWN` is by design, because `ADMIN_DOWN` caches should probably still be able to run ORT. If the cache can't run ORT, it is more likely `OFFLINE` than `ADMIN_DOWN`. If there are "stuck" `ADMIN_DOWN` caches causing revalidations to not propagate, then they should likely be `OFFLINE` instead.
   
   We wouldn't want to set an `ADMIN_DOWN` cache back to `REPORTED` without the cache having processed all the revalidations yet, so for that reason we should probably continue to include `ADMIN_DOWN` caches in `parent_reval_pending/parent_pending`.
