Google has confirmed that they are performing “infrastructure updates” to the Google Search Console. These infrastructure updates may impact the reporting within the interface, so you may not be able to get accurate information from the Google Search Console during this upgrade.
Google has not said when the upgrade will be finished, but rather it is “ongoing,” and they “thank you for your patience and hope to resume logging shortly.”
Google did add that the data within the Search Analytics report “should not be affected” by 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.
Of course, many are hopeful that this upgrade is Google’s effort to launch a year of data in the Search Console, something Google promised us many many years ago. But that might just be wishful thinking.
