So, at the 2012 I/O conference Google announced there were 425million gmail users. I'll tack an extra 75million to make things an even 500mil for growth over the last year. That's 12million affected users.

500 million * 0.00024 = 120,000

It's been updated to say "less than 50% of Gmail users" now. We're seeing it across most/all of our accounts.

Based on my experience this morning, I'd say that 15% of our 300 or so Gmail users over about 25 domains were effected. In my opinion, their initial estimate was way too low and seemed dismissive.
