+Potential slow database update during upgrade
+---------------------------------------------
+
+Synapse 1.12.0 includes a database update which is run as part of the upgrade,
+and which may take some time (several hours in the case of a large
+server). Synapse will not respond to HTTP requests while this update is taking
+place. For imformation on seeing if you are affected, and workaround if you
+are, see the [upgrade notes](UPGRADE.rst#upgrading-to-v1120).
