Update 2: Here's Google's response, though it's in the context of this being a Gmail outage, when it was pretty clearly an across-the-board service disruption:

On Monday, 10 December 2012, we experienced an issue with Gmail and some users experienced slow performance or errors. For everyone who was affected, we apologize - we know you count on Google to work for you, and we worked hard to restore normal operation for you.
