@jillian, I sincerely believe that if the requirements are open to interpretation in any way, you should at a minimum avoid revoking certificates until 2020-03-04T23:59Z to give people at least another 23.5 hours to fix their certs, if that falls within the interpretation of the regulations to which LE are bound.
In fact, having read the incident report, if the bug was confirmed at 2020-02-29 03:08 UTC, then 5 days should be 2020-03-05 03:08 UTC.
How long does LE expect the revocation process to take?
