Hi,
Same here Saturday morning - was due for the 9-10th May free upgrade.
BT Profile says 38.72Mbps (Achieved 33) for downstream and 10Mbps (8.06 achieved) for upstream
TBB Stest says 30.5 down, 6.9 up.
Maybe delayed due to bank holidays - my bins are still out on the driveway
Didn't see the zen service alert saying there was an issue with the free regrade though
Cheers
Andy
