What is the purpose of the Synchronisation between upstream and downstream server?

Downstream servers synchronize updates from the upstream WSUS server. There are two forms of downstream servers: autonomous and replica. An autonomous server synchronizes the same updates as the upstream server; however, it can create its own target groups and manage its own approvals.

How often does WSUS check for updates?

every 22 hours
By default, client computers contact their managing WSUS server every 22 hours. This interval is configurable through Group Policy or by editing registry settings. The data the report returns can be presented in three different views: the status of an update at a high level, by computer group, or by computer.
