Can replicas retry for a longer time?
We had a bad situation with our prod cluster. There was a DNS failure in AWS and all the replicas went “brown”. Only the leaders were taking traffic.
If the replicas had continued to attempt recovery every five minutes or so, they would have come back online automatically.
Is there a way to configure that?

Assuming this is SolrCloud, the replicas retry upto 500 times and wait an
exponentially increasing time between retries starting from 2 seconds and
upto a minute. Did that not happen in your case? Did the JVM had DNS ttls
set?
