Donatewiki currently redirects users in Switzerland to pages on wmfwiki like https://wikimediafoundation.org/wiki/WMFJA1/CH. These pages will be going away soon, and Wikimedia CH have long hosted their own landing pages (which have already been used to receive traffic from banners).
We should update donatewiki to redirect Swiss users to the following pages. I confirmed this with @Ilario from the chapter.
- English: https://www.wikimedia.ch/donate/
- German: https://www.wikimedia.ch/de/spenden/
- French: https://www.wikimedia.ch/fr/faire-un-don/
- Italian: https://www.wikimedia.ch/it/effettuate-una-donazione/
I found some documentation at https://wikitech.wikimedia.org/wiki/Donate.wikimedia.org#Chapter_Redirects but it was last updated in 2013 so may not be current.
