It may occur that you have made a booking for a terminal for a particular time slot and your login does not appear in the allocation list of the appropriate infoterm. The booking system makes its machine allocations on a first booked first allocated basis using only those machines that are `up' (ie working) at the time of allocation. Bookings, on the other hand, are accepted on the basis of the number of machines that are physically present in the laboratories. However, the number of machines that are physically present in a laboratory and the number of machines that are `up' and available for use in a laboratory, may not necessarily be the same at allocation time. For this reason, the booking system will warn users who book the last few available terminals in a lab, that their bookings might not be able to be honoured.
When a laboratory is fully booked and some machines in that laboratory are down and unavailable for use, the booking system is unable to honour all the bookings for that laboratory. The bookings that were the last to be made for that laboratory will not be honoured. The booking system will refund the tokens that were used to make those bookings that are dishonoured.Loc Van Huynh 2007-03-15
