dec 17, 2020 - December 2020 Core Update

Description:

Google announced a Core Update that appeared to roll out quickly, with the bulk of the impact hitting on December 3rd. MozCast hit 112°F, on par with the March 2020 Core Update and August 2018 "Medic" Update. Some sites reported reversals a few days later, but this seems to have been limited.
