Technically (well politically) satellite ISPs have to enforce the shutdown as well. You'd need a two-way contract where both upstream and downstream is via satellite, many contracts are cheaper when the upstream is via phone line. Have a look at https://www.eutelsat.com/ https://www.eutelsat.com/ Too Way (there are various resellers). Expect cost of 500 Euro for hardware, 60 Euro/month for 50Mbit down, 2Mbit up.
