Right, sorry once again for the technical issues we experienced with this page earlier.
We hope to bring you a full, glitch-free service for qualifying from 13:00 BST, with the session itself off at 14:00.
I, for one, have every faith our technical boffins can keep this show on the road.

BBC Radio 5 live commentatorThis is the kind of track McLaren is very strong at, even with that Honda engine in the back.
They've got to really take advantage of that fact this weekend, because the car is clearly working well and that Honda engine isn't comprising things too much.

FP3 ends with Max Vertstappen fastest on a 1:41.829, but it's as close as you like at the top - just a tenth of a second between the top three.
Full times to come.

Alonso briefly put the McLaren into third place before Hamilton improved.
The Spaniard is fourth at the moment, just half a second off Verstappen. Team-mate Vandoorne is just a tenth back in fifth.

Alex Withington: Absolutely mighty laps from Fernando Alonso and Nico Hulkenberg. The cream rising to the top.
Daniel Eckersley:Good to know Alonso's on it. I've got a whole pound on him to make the podium this weekend.
Amit Mandalia: How key is this race for title fight? Mercedes downplaying their chances so if they beat Ferrari surely more confident into final races?

Lewis Hamilton goes just a tenth slower than leader Verstappen.

Andrew Benson
BBC Sport’s chief F1 writer in SingaoreThe ill-fated McLaren-Honda partnership was finally formally dissolved on Friday, even if the unhappy partners have to share a house for another couple of months. Honda are walking off hand-in-hand with Red Bull’s junior team Toro Rosso - and quite likely Red Bull, too, in 2019 - but their sense of perspective seems to have deserted them.
Their operations officer Katsuhide Moriyama was in the official news conference on Friday and he claimed the company’s goal for 2018 was “to fight for the top three at the front of the grid”. This caused a few raised eyebrows, you could say. As one senior figure put it later: “Toro Rosso wouldn't be in the top three even if they had a Mercedes engine.” ‘Delusional’ does not even begin to cover it.

"The car is shifting by itself," Max Verstappen informs his team over the radio.
He's bringing the car back to the pit lane.
