This resource returns whether your ArcGIS Enterprise deployment has been set to read-only mode. When enabled, the Enterprise portal, connected hosting and federated servers, and ArcGIS Data Stores are all set into read-only mode. During this time, most POST requests and administrative functions are blocked. Users within your organization will still be able to view and access your content; however, attempts to create, modify or delete content or site properties will be blocked. To learn more about read-only mode, see Read-only mode in ArcGIS Enterprise.


The Update operation will only affect servers that had not previously been set to read-only mode. When Update is used to enable read-only mode, servers that were originally set to read-only mode will not be affected. When Update is used to disable read-only mode, those same servers will be unaffected and will remain in read-only mode.
