Last week, Google confirmed that they are performing infrastructure updates to Google Search Console. They have said that these updates may interrupt and effect reporting within the interface and that users may not get accurate results during this time.
Google have not said when the update will be complete, but rather that the updates are ‘ongoing’, but hope to resume normal logging soon.
It was added that data within the Search Analytics report should be ‘unaffected’ by the work going on, but that other reports and sections may have some data logging issues over the next few weeks.
The work began on November 1st, and is expected to carry on for at least the rest of the month.
