<br>
You mean something similar to that option in drouting ? If so,
yes, it would make sense IMO.<br>

<br>
I guess this will be a good topic (DS and K8S) for the
OpenSIPS Summit in Athens - I think this is the 3rd time in
the last week coming across it :)<br>
<br>
Unfortunately there is no way to skip at the moment that DNS
failure when loading the destinations :(....even more, there
some code that relies on the fact that there is an "IP"
attached to any destination.....And I just checked, a local
error in sending the ping (like the DNS err) does not
results in marking the destination as failed or so..... so
it is not so straight as ignoring the DNS error.<br>
<br>
Best regards,<br>
