Better uptime for connections
This can be used in place of the Relay, which is a manual feature.
Whenever a peer-to-peer connection fails, the failover will take over the connection, acting as a relay between the two machines, giving your network a higher overall uptime.
Some machines just aren’t reachable with p2p. The failover handles these scenarios automatically. A relay can do this too, but must be configured manually, and you don’t always know when this situation will occur.
If you set up multiple failover servers, Netmaker will select the fastest one for any peer-to-peer connection, checking the latency of the connections.
