It’s been confirmed by Google that they are performing “infrastructure updates” to the Google Search Console. These infrastrucutre updates might impact the reporting within the interface, so you may not be able to get accurate information from the Google Search Console during this update.
It hasn’t been stated yet by Google on when the update will be finished, but has instead said that it is “ongoing” and that they “thank you for your patience and hope to resume logging shortly.”
Google added that they data found within the Search Analytics report “should not be affected”but these upgrades.
But that in the other reports and sections, it may “prevent data logging in some reports for the next few weeks.”
This began on November 1, 2016 and might last for most of the month.
