gmail weirdness

My fiancee’s Gmail account is showing 1000000MB (1TB) of space available now. Mine is still showing 1000MB (1GB). Weird. Apparently these aren’t isolated cases, as a lot of people on Orkut are posting that they’re showing 1000000MB of available space too, and many others posting that they’re still showing 1000MB. I wonder if this is just a temporary glitch in the Gmail system, or Google is trying something new.

As far as I can tell, there is no relationship between the way that the invite was received (from Google employee or via other Gmail user) and whether or not the account shows 1000000MB of available space. Account usage also doesn’t appear to be a factor. As far as I can tell, it’s completely random.
