Hi We are running ISC DNS Bind Version 9.18.10 ( will soon be moving to 9.18.11) on our Linux Servers.
DNS resolution in general seems to work just fine as expected. It seems we have intermittent issues resolving "labor.upload.akamai.com" and then some scripts fail. It is clear that the failure of the script is due to DNS name lookup. Not sure if this is an issue that needs to be looked up at our end ( since DNS as such is working just fine for all the rest of the name resolution) or things are not configured properly at other end as far as how this DNS record is published and due to which I see the behavior of intermittent dns name lookup failure. Any pointers would be appreciated.
