Change Windows and Notifications of Works

1 hour vulnerable window per week during standard hours (Tuesday - 8:00 – 9:00am)We have a weekly change window from Wednesday 17:30 to Thursday 08:00 (14.5 hour window).  If we are completing non-disruptive maintenance (which involves no downtime or impact on users) this will take place during this period with no notification.

• Planned outage / downtime – notification for planned outages/downtime during a vulnerable period will be sent 2 weeks prior to outage6 days beforehand (the Thursday before). Then a reminder will be sent 1 week and the day before the outage.
• Unplanned outage / downtime – As soon as possible, subsequent updates to be sent as soon as more information becomes available, or workaround is implemented.
