How much time in advance should users be informed of an upcoming maintenance on app?

1. How do you announce a scheduled maintenance?
2. How do you announce scheduled network maintenance to your users?

How do you announce a scheduled maintenance?

Depending on the expected impact, send one a week ahead of time, one a few days ahead of time, one the day before, and one the day of the planned downtime. Not all of your users will remember a single notice, so use multiple notices to keep reminding them as the scheduled time gets closer.

How do you announce scheduled network maintenance to your users?

Please be advised that there will be scheduled downtime across our network from (date/time) to (date/time). This is because we are performing work on (functions/parts of the network). We apologize for any inconvenience. For more information, or if you have any questions, please contact the IT Team at (contact details).
