If the end customer relies on a reliable Internet connection (e.g. home working), the Internet connection must be redundant via two different, independent Internet providers (for example: Swisscom <-> UPC-Sunrise). See also:

It is common for an internet connection to be implemented for a Swiss private household via:
1.) Fiber optic (FTTH -> AON)
2.) Fiber optic (FTTH -> PON)
3.) Television cable network (EuroDOCSIS)
3.) Telephone cable (ADSL, VDSL, G.Fast)
4.) Mobile communications
5.) Long-distance WLAN (WLAN radio link)
6.) Satellite communication via LEO satellites (for example: Starlink)
7.) Satellite communication via GEO satellite(s)
The number indicates the order in which connection technology is to be preferred.
