@ -43,6 +43,17 @@ When the _Leader_ goes down, this is automatically detected by the _Agency_

{% hint 'info' %}
The different instances participating in an Active Failover setup are supposed
to be run in the same _Data Center_ (DC), with a reliable high-speed network
connection between all the machines participating in the Active Failover setup.
Multi-datacenter Active Failover setups are currently not supported.
A multi-datacenter solution currently supported is the Datacenter to Datacenter replication
(DC2DC) among ArangoDB Clusters. See [DC2DC](../DC2DC/README.md) chapter for details.
