On Sunday July 26, 2015 at 11:35 am, the Dupuis Hall data centre’s power was automatically shut down due to fire detection sensors triggering the release of the room's fire suppression system. The root cause has been identified as a compressor oil leak in one of the air conditioning units. 

Power was restored to the room just before 4 pm, following inspection by both the Kingston Fire Department and Queen's Environmental Health and Safety.

All systems have since been restored.
