Delivery rates to Apple domains have returned to normal with no further elevated delays or bounces. We will perform any necessary post-incident cleanup of suppression lists to ensure no recipients were incorrectly suppressed during the outage. NOTE: As of Monday April 5th at 9PM EDT the cleanup has been completed. All recipient addresses to Apple or Apple Private Relay domains that were suppressed during Apple's incident window were removed.
