With the move to ever shorter certs the risk to letsencrypt having an outage is higher.

It would be nice to read more about what the organization is doing around resilience engineering so we can continue to be confident in depending on it issuing renewals in time.

Do you publish any of this? DR plans? Etc.

I don't mean for this to be a negative - really impressed by LE - but we've had a lot of Cloudflare outages recently and my mind is on vendor reliability & risk at the moment.
