This is the default page of a server called wmch-dicoado01 and its job is to keep the DicoAdo.org project online for years and years and years.
Note: DicoAdo is an amazing independent community writing contents, and Wikimedia CH is just the service provider owner of this server.
If you think you should not see this page, or if you have any question, feel free to open a Task here to DicoAdo:
