## Server Blocklist
This page allows to block all communications (inbound and outbound) with a specific domain name.

## Federation Statistics ## Federation Statistics
The federation statistics page gives you a short summery of the nodes/servers/pods of the decentralized social network federation your node knows. The federation statistics page gives you a short summery of the nodes/servers/pods of the decentralized social network federation your node knows.
