SEOPTI, the last two weeks we have noticed record low crawling on our biggest sites. Also GWT data is the most behind we have ever seen. Crawl errors havent been updated since Instant went live and page speed hasnt been updated since the 3rd or something.
Maybe Instant put to much processing tax on the system so they scaled back crawling and GWT until they can get it sorted out. Didnt we see reports a week or so ago of Google crashing? Just a theory.
