Final status: This issue has been resolved and telemetry indicates that over 99 percent of impacted emails have been unblocked and automatically replayed. Customers have also reported resolution, and we\u2019ve confirmed that new emails are sending as expected.<\/p>\n

Scope of impact: Impact was specific to some users who are served through the affected infrastructure.<\/p>\n

Start time: Monday, August 26, 2024, at 12:50 PM UTC<\/p>\n
