Hi @mariemqara1
This looks to be a duplicate question to: https://www.servicenow.com/community/service-management-forum/upgrade-downtime/m-p/3052829#M36922
My response to this as posted on the above duplicate is:
This is an interesting question which really depends on the individual instance itself - how customized (or not) the instance is, what integration or services are running etc. Sadly, it's not a 1-size fits all scenario.
For context, check the following link on 'Upgrades' - remembering that an 'upgrade' is upgrading the ServiceNow version form one to another.
From the link:
"During an upgrade, your performance may be impacted because your nodes initiate the distribution upgrade. All nodes are restarted during an upgrade, but your multi-node instances are available during an upgrade because ServiceNow instances operate on a multi-node system. This multi-node system staggers node distribution upgrades, ensuring that there is at least one active pair of nodes for multi-node instances during an upgrade.
To help you set accurate expectations for performance during upgrades, be aware of the differences between the nodes on your non-production and production instances. Instances with one node experience a short period of downtime during the upgrade, but multi-node instances do not have UI downtime. For details on your nodes and their status, see the Upgrade Progress screen."
Re Updates - ServiceNow provide communications (As in emails which are also available in the ServiceNow Support site) and advise explicitly if an update affects downtime or not.
To help others (or for me to help you more directly), please mark this response correct by clicking on Accept as Solution and/or Kudos.
Thanks, Robbie
