Not sure about the feeds but those watching/commentating live overnight say the count, via various holds, including a -10 minute one, got down to T-33 seconds before it's planned cutoff.
There was then a planned recycle back
out to the T-10 minute point to give the team another run at a simulated terminal count from that point.
All should be revealed by officials later but ATM and
AFAIK it's being deemed succesful.
