Summary AI Generated
A bug in Centera Security's DMARC monitoring incorrectly identified many domains as having empty DMARC records, triggering a flood of erroneous change notifications when valid records were re-detected. No actual email authentication was affected, and the false alerts required no action from users. The incorrect notifications were halted and a root cause investigation was initiated.
Earlier today, a bug in our DMARC monitoring incorrectly treated many domains as having an empty DMARC record. When valid records were detected again, our system sent change notifications that should not have been sent.
We apologize for the noise and any concern this caused. No action is required on your side, and there is no indication that your email authentication was affected.
We have stopped the incorrect notifications and are investigating the root cause.
Thank you for your patience.
