Due to the natural of technology and its development, it has become standard practice throughout many organisations to have regular, scheduled, updates to systems. By taking this approach, there is a reduced risk to functionality and other systems. Users can also plan to avoid usage during these maintenance periods.The dates below indicate an expectation of scheduled maintenance which may disrupt access and functionality of The Cochrane Library.(The standard schedule for developer activities commences at 10am (UK Time), and continue for 2 hours, though this is subject to change).These dates are subject to change.Notifications of the expected downtime will be sent out in the week prior to the expected downtime, to users on the Cochrane 'lists' (TSCs, MEs and Cochrane Library User Group).
