Let's Encrypt conducted a planned incident drill that required stopping certificate issuance on their staging environment for compliance obligations, lasting 3.1 hours. The acme-staging-v02.api.letsencrypt.org staging service was affected, with issuance being disabled twice during the drill period. Service was restored with authorizations and preexisting orders cleared, requiring users to retry issuance with new orders if they encountered errors.
