The site lost it's site links that google showed, the PR was dropped to 0 (from 3) and in webmaster tools, the Crawl Rate and the Crawled Pages per day dropped to 1/3 to what they were the previous day.
I just posted the following thought in the linked thread, but wanted to post it here for people who haven't been around as long or seen this type of an update before.
The above describes things very similar to what we used to see quite a bit of during updates, because certain systems and filters would get turned off while the update was in progress and then get added back in after it was completed.
