Yeah, Pro.Coinbase.
It is back to normal for me too.
However the whole of this morning the books for BTC were frozen, no movement.
I even placed a limit sell - and it just said 'pending' for about an hour - I wasn't able to cancel it either which was alarming.
My coinbase wallet also lost track of my Euros, saying I had 0 available. (which wasn't true.)
But it is back now.
I've lost a bit of faith in coinbase as a result of this however... had something happened that needed acting on - well I wouldn't have been able to do a thing.
P.S - looking at the chart within pro.coinbase there is a big gap between 8.00am to 11.30 am (and greeted by a big red candle. sigh...)
