+# Unsplitting Gerrit
+
+Gerrit's natural focus on scalability relies on being able to run clusters with
+multiple nodes and reliably serving traffic from each node.
+Observability over how the nodes are in sync, when they start to drift apart
+and being able to quickly investigate and fix issues when they arise becomes
+critical to the correct operation of the cluster.
+
+In this talk I'll go over the main hurdles, what problems we have found and
+what solution we have put in place solutions to ensure Gerrit Admins are
+always on top of the installation.
