Over the past couple of days we've made some promising developments with our problem with PC Bookings. To recap, you could book a PC, but your reservation didn't always work which led us to decide to temporarily disable advanced bookings.
However, we've made some progress and it is now possible to book computers a day in advance. Hopefully we will be able to increase it back to two days if the work we've done proves successful, but for now this is a precautionary measure. We'll keep working at it and let you know how we get on.
