[liberationtech] Gmail SSL Certificate Churn?

[Nick M. Daly]

Hi folks, can you help me understand how to interpret this data?  It
appears that Gmail's SSL certificate changed fairly frequently during
the month of December.  That seems wrong to me.  What's this all mean?

The weirdest part isn't how the 0E:66... certificate disappeared on
November 20th (or December 5th), but how it came back into circulation
on or around December 20th.

Thanks for any clarification you can offer on this situation,
Nick
