Google slow to index pages

[punchseo]

Hi

We've recently had a product launch for one of our clients. Historically speaking Google has been quick to respond, i.e when the page for the product goes live it's indexed and performing for branded terms within 10 minutes (without 'Fetch and Render').

This time however, we found that it took Google over an hour to index the pages. we found initially that press coverage ranked until we were indexed. Nothing major had changed in terms of the page structure, content, internal linking etc; these were brand new pages, with new product content.

Has anyone ever experienced Google having an 'off' day or being uncharacteristically slow with indexing? We do have a few ideas what could have caused this, but we were interested to see if anyone else had experienced this sort of change in Google's behaviour, either recently or previously?

Thanks.
