Gmail disk space

Um, wow?  Did Gmail just double its disk quota overnight?  It’s showing a 6341 MB, and I would have sworn it was about 2800 MB a few days ago.  I’m back down to 26% utilization, and hoping against hope that the quotas continue to grow faster than my email volume (I’ve already turned off every mailing list that’s being archived on a website, as that was quickly creeping up on the quota.)

Also, I’m very surprised that quotas is the plural of quota, and not quotae or something.
