Welcome to Crawl or No Crawl during this August Core update.
The extra incident in the Ranking subsystem of the indexation system was officially closed earlier this morning. Other than “opps” and “we got it” - no info provided on what the issue was or how it was recognized as a problem.
But I do have some indexation results on the testing that unintentionally started on the day of the update announcement. I’ve got a ways to go to call it proof, but this looks like evidence that there is a “there there”.
