In the past Devnet sandbox, the maximum reservation duration is 4 hours and I usually didn't have much problem accessing the CML sandbox. However, in the new Torque system, the maximum reservation duration is up to 8 days. It is almost impossible to access the CML sandbox.
Given that most of us, if not all, can't possibly use the Sandbox 24/7, suggest that the Sandbox team reduces the maximum reservation period to a much shorter period (e.g. 8 hours), so that the Sandbox resources can be more efficiently utilized and made more available to everyone.
