Previously, updating a site connection via the REST API (PUT /objects/site_connection/{site_id}) silently discarded any site-specific global settings (configured under Setup > Distributed Monitoring > site > "Site specific global settings") that had been set for that site. Even a REST API request that only touched an unrelated field, like the alias, would wipe these overrides.

This has been fixed - such settings now survive a REST API update, the same way they already do when the site connection is edited via Setup.
