Bringing the total number of affected users down to 38,660.
Not nothing, but not a lot either. My company has an exchange server for 200 or so people, and at any one point there are probably one or two people who are waiting for a password reset, errors with Calendar, public folder permissions errors, or other human error on the part of the helpdesk interns. That's a 100x increase from Google's error rate in this scenario, but it's perfectly acceptable within the context of our organisation.
That's why we have tape backups (which can take some time / effort to restore from). I think the difference is that if a user at my company has a problem they can call a human being and be told that someone is working on it, but with Google you can't do that.
