I was just on the Hilton Honors site and MyPoints is still there. However, it still doesn't show HH on the MyPoints site. I know it was there less than a week ago because I was only 10 points short of being able to transfer to HH and was waiting for a couple of surveys to post to MyPoints.
Hopefully, it is just a glitch and will come back. I feel better since it is still on Hilton's site, but that could be a lack of updating.
