[knot-dns-users] policy.rrsig-refresh in Knot 3.2.0

Good morning, In Knot 3.2.0 the rrsig-refresh default changed, excerpt changlog: knotd: default value for 'policy.rrsig-refresh' is propagation delay + zone maximum TTL I'd like to understand the rationale behind this change and whether or not we should tune this parameter in our deployment. We currently have monitoring in place to ensure that we always serve valid signatures. In my understanding with the old defaults < 3.2.0 of rrsig-refresh of 7d and rrsig-lifetime of 14d, we always ended up with signatures that were at least valid for 7 days. As I understand, with the new defaults, signatures might be refreshed way closer to their expiry date. This makes me a bit uneasy, as if there are issues with signing this gives us hardly any time to react and fix potential issues before the current signatures expire. I assume setting rrsig-refresh explicitly to 7d would restore the old behavior, but I'm wondering if this is somehow bad practice and if we are overly paranoid with our monitoring. How do other people handle this? Are there any downsides of setting a higher value of rrsig-refresh that we are not aware of? Regards André
