You have a limited amount of quota to use on your machine. The quota is incremented each week based on the table below. While every effort has been made to automate as much as possible, we can’t always account for closing down labs within the current functionality offered by ALS. Linux VMs in particular will not abide by automated shutdowns.
We strongly advise you close your lab at the end of each session, not doing so will result in your lab being left running – which will eat into your allocated quota and eventually mean you won't have access to the lab.
At the bottom of the lab tile is a toggle. At the end of your session, it will say ‘Running’ – click it to stop your lab.
