Note that renewing certificates is generally exempt from rate limits: https://letsencrypt.org/docs/rate-limits/#limit-exemptions-f...

We are working on further improvements to our rate limits, including adding more automation to how we adjust them. We're not ready to announce that yet.

We wanted to get this post out as soon as we'd decided on a timeline so everyone's on the same page here.
