In general, reason for any service outage would need explanation by the service provider.  Service provisioning is so complicated (layers upon layers) that what's seen on the surface is hardly representative of what's inside.

A rule from years of developing monitoring scripts: It's one thing to detect and measure symptoms, it's an entirely different thing to make a diagnosis.

    I had several bounce mails today from my Gmail to IETF's mail. It's weird. 
    	The response from the remote server was:
    	550 5.7.1 mail w9G8HQ5a028992 from 2607:f8b0:4864:20::72a rejected by DCC
    The bounce may irrelevant with KSK. But an question came up to my mind that how can a user identify a failure caused by KSK rollover?
