Google announced this morning on Twitter that some reports within Google Search Console are delayed. They are delayed because of pipeline issues with getting data from sources within Google. The specific reports that are more delayed than normal include AMP, Rich Results / Structured Data, Hreflang, Index Coverage, & Mobile Usability.
I checked a few reports myself and while some of those reports are more delayed than normal, some are not. For example, the Index Coverage report goes up to a week ago, October 12th, which is more delayed than normal. But AMP and Mobile Usability goes to Wednesday, October 17th, which is a normal two day delay.
So not all are seeing these report delays on all reports.
Google is aware of these reporting delays and they have no impact on your rankings in search.
Some Search Console reports are currently a bit more delayed due to issues in the reporting pipeline (AMP, Rich Results / Structured Data, Hreflang, Index Coverage, & Mobile Usability). This doesn’t affect your site in search. We’ll let you know when things are back up to speed!
