Gmail Capacity: 1 Million MB?

When I logged into my Gmail account today, I found the following message displayed at the bottom of the screen:

Just yesterday, the message correctly indicated that 16 MB was 2% (rounding up) of my 1000 MB capacity. So, what gives? Is this message an error? Or am I really going to get a million megabytes of storage for my email? Now, that would be something.

Bummer. I just logged in this morning (5/19) to find that the situation has been “fixed.” Looks like I’m back to my puny gigabyte.
