+----------------------------------
+Dear {{GATEWAY_NAME}} user,
+
+We want to make you aware that this Thursday (6/29) at 5:00pm CEST, the workspace service will be set in read-only mode until the next morning Friday 30th at 10:00am CEST.
+
+Please note, during this maintenance window, the Workspace will be set read-only for “human” users, while all operations around the service performed programmatically, 
+including execution of experiments can be executed and will be resumed after about 2 hours since the maintenance window.
+
+We will be using this time to add more capacity and speed up the overall service. 
+To ensure uptime and stability of the infrastructure, we are performing this upgrade on our infrastructure during the night so that we can ensure a smooth transition.
+
+We appreciate your patience and understanding. We will do our absolute best to perform this operation as fast as humanly possible.
+
+If you wish to know the progress follow D4Science on Twitter at https://twitter.com/d4science
