Review comment:
hi @srowen
Now I understand what you mean, "here" means this PR or jira ticket (please
correct me if I miss understood you). Then no worries, I'll keep the retries
only in this one and then start a new PR/Jira process to discuss the DNS, and
see what and where we can do.
In my opinion retries make sense, avoid rescheduling something for a
transient error that is recoverable is helpful, this is not multi layered
system so it can't storm out.
I've re-written history into a single commit to make it cleaner.
