Flying Club not available over the weekend

Does anyone know why the site was not available to pax or even the FC agents over the weekend ?
The site looks (and behaves) exactly the same as before so wonder what they were up to ?

There was something on the front page of the VS website (which has now gone) over the weekend saying 'maintenance' and FC would be unavailable and this included not being able to access rewards / upgrades and this applied to staff as well

As far as I know the site was still open for normal bookings/
