Certainly progress. What I find interesting is that the order I placed just before the 'maintenance' started, and in relation to which I received emails saying the documents were ready while the website was down, has now been fulfilled. (I have downloaded everything quickly - just in case!) As with other contributors, some of my previous orders are now shown, a few available to download, most pending.
Interestingly, I managed to put in an order for a single will (I'm prepared to risk £1.50) when the website came back up, even though most of it didn't work. This is now shown under My Orders, but is pending.
Judging by another user's experience posted above, they seem to be dealing with new orders quickly, but there may be some issues with orders placed during the recent problem period.
I await further developments.
