+Hi {{proprio}},
+
+Your upload has been temporarily limited due to the anormaly big amount of data
+you uploaded toward the outside of the Crans network. 
+({{upload}} Mo within the last 24h)
+
+If this event were to take place too often, you would be totaly disconnected 
+for a longer period. It is thus your duty to check your computer usage so it 
+doesn't upload too many data in the future. 
+
+{% if reco_url %}
+To remove the upload limitation, please consult : 
+{{ reco_url }} .
+{% endif %}
+
+For more informations, please consult :

+
+In case you have any question, please contact disconnect@crans.org.
+
+N.B. : Upload consists of sending data to computers not connected to Crans 
+network.
