The primary DNS server that our Chicago clusters use is down. There is no outage in services as the secondary DNS server is picking up the slack. We are modifying the Primary DNS of all servers in the Chicago cluster to a ensure redundancy and keep services up and running.
No user changes are required as this is a transparent fix.
We will issue a rolling restart with the changes tonight at midnight Central Standard Time.
Only the Chicago cluster will be impacted. Downtime will be less than one second. If you are disconnected from the Chicago cluster around this time, you will be able to immediately reconnect and resume service.
There are no security implications to this change, speeds resolving domains while connected to the Chicago cluster will improve after the change goes live.
