Hi

I'm a employee of a good known E-Commerce site here in switzerland and I would like to share some thoughts from my side if that's okay for all. I hope I understood well enough what you plan. Otherwise just ignore what I just wrote :)

That's correct, the customer doesn't need to the reach the website from outsite switzerland normaly. But there're many 3rd-Party Provider for Newsletter, Monitoring etc. and distributors that need to be able to resolve digitec.ch outside of switzerland for example. (because there server are not located in switzerland) Mostly it's dispensable if they can't reach the website or a ftp server for some minutes, but if they can't access the page for days the E-Commerce Site will have issue with orders, product availability, newsletter shipping etc. Also some 3rd-Party Scripts may use a dns lookup and would fail then. There's also a possibilty that the employee reach the internet via a proxy outside of switzerland (due to a enterprise policy) so they wouldn't be able to access there site and couldn't work at all.

Of course if the site isn't available at all it's not a good experience for the customer and they may order there article on a other onlineshop, but if the website is online and doesn't work properly that's also not a optimal solution either.

Addiontally to the fact that more and more E-Commerce Websites use DDoS-Protection services like akamai or cloudflare, only about half hosting there website on server in switzerland.
