This morning at 6:19:51am, the SEC accepted for publication Google's IPO prospectus. Sometime later they actually published it and PubSub.com notified me of it at 6:25:29am -- just over five minutes later. At 6:42:55am, almost 23 minutes after the SEC released the prospectus and 17 minutes after PubSub had alerted me about it, I finally got a notification from Google that the prospectus had been released. Note: Google used a Morgan Stanley mail server (picfbh6.ms.com) to send the announcement.
I had thought that as a registered bidder on Google shares (I didn't actually buy any), that I would be receiving notifications about the IPO from Google much faster than if I had relied on other channels. However, throughout the process of the auction, as Google made new filings and modified older ones, I consistently received notifications from PubSub.com about 20 to 30 minutes before I got similar notifications "straight from the horse's mouth" -- i.e. from Google itself.
