    you may try to check if pool is available using active_members and send http response (when no pool is available) using HTTP::respond. active_members   https://clouddocs.f5.com/api/irules/active_members.html HTTP::respond   https://clouddocs.f5.com/api/irules/HTTP__respond.html

    I think priority groups would be a better way to address this, with an iRule just for a sorry response. So one pool, 3 different priority groups, 1 min per group.
