It is noticed that it takes a long time for DNS to replicate at APIGEE/AWS. Does a rolling restart of you Message-Processors help clear the DNS cache? Or does the cache get flushed in X time?
Solved! Go to Solution.
It depends and usually the records are cached for longer duration. When you observe this behavior
try,
> dig <new_domain_name>
on the MP instance, if it resolves to the new IP then DNS propagation reached that instance but the MP process is not seeing this change because of the cache. In this case, you could restart the MP
If the 'dig' does not show the new IP, wait for it to reflect the change before restarting MPs
