Veeam syncing data via WireGuard to my parents server each night. I can't have my Veeam backups or Syncthing running at max bandwidth between 08:00 and 00:00 as it affects both mine. Developing Syncthing costs money. Currently not as compensation for the developers — that's all volunteer work — but in domain and hosting fees for the various servers we need to run the operation such as discovery servers, build servers and this website. Your donations help fund these costs.

When global discovery is enabled, Syncthing sends an announcement every 30 minutes to the global discovery servers so that they can keep a mapping between your device ID and external IP. The announcement contain the device ID and listening port(s). Also, when connecting to other devices that have not been seen on the local network, a query is sent to the global discovery servers containing the device ID of the requested device. The connection to the discovery server is encrypted using TLS and the discovery server certificate is verified, so the contents of the query should be considered private between the device and the discovery server. The discovery servers are currently hosted by @calmh <>. Global discovery defaults to on.

When turned off, devices with dynamic addresses not on the local network cannot be found and connected to.

An eavesdropper on the Internet can deduce which machines are running Syncthing with global discovery enabled, and what their device IDs are.

The operator of the discovery server can map arbitrary device addresses to IP addresses, and deduce which devices are connected to each other.

If a different global discovery server is configured, no data is sent to the default global discovery servers.
