A marked day is a UTC day the feed listed this address. The feed keeps a listener for up to 90 days after its last confirmation, so a listed day is not a confirmation. A listener no longer in the feed is drawn to its last confirmation.

The names above are what the certificate asserts, signed by the issuer it names, which may be a public certificate authority, a private one, or one a builder ships. This site verifies none of it, so treat a name here as a lead to investigate, never an attribution.
