Remember connection via satellite 
But. isn't that even easier to blackout than any other route??? We don't put sats up the, the Governors do, and we couldn't keep 'em there cos we aren't military.I think he's talking about the case for example if Iran's government black out the Internet for the people of Iran, then satellite would definitely be an option. Iranian government can't take down other country's satellites. Satellite companies can provide people in Iran satellite internet (though I guess you have to smuggle equipment into Iran first).
Actually they can take out satellites by jamming. This jamming can be local on the downlink side (possible to get around) or be on the uplink side (much harder to get around).

If you have good techs with equipment you can do microwave links in some areas to bridge.
