Hi, bind 9.10.3_p4 with this global option: forward first; forwarders { 8.8.8.8; }; If i dig from localhost or any client and 8.8.8.8 answers all is ok but if 8.8.8.8 is unreachable or it doesn't respond, bind doesn't fallback on himslef asking to root server etc . This is not expected. Anyone with this behavior ? best regards Marco
