There was a problem with the stats server over the night. We got to it first thing in the morning (around 6:30am pacific time), but it looks like a few stats updates were missed. The missed data is backed up on another machine and we can re-enter it. However, we typically take a couple of days to re-enter it, to make sure it is done right.
So, the bottom line is that the stats system is back up, will we recredit some missing WUs not credited over the night, but this will take a couple of days to complete. Sorry for the delay on the recredit, but it's good to make sure we do it right, rather than in a rush.
