I assumed that the applications would take absent records into consideration instead of waiting and timing out before responding with data. Trying to troubleshoot this issue from the limited visibility is difficult ; the latency the application is introducing is abstracted (unless I am unaware of that troubleshooting technique).
When you mis-place your keys do you only look in one place and then give up? The calling server does not know there is "no" record until it exhausts its list of DNS servers, which is probably what is introducing the delay you are seeing (each server trying to find a PTR with each of its upsteams) until they all time out... -- Larry Smith lesmith@ecsis.net
