You can jam a cell phone but jam the internet in a specific locale? You could totally block specific IP addresses, I suppose. But, the whole thing sounds too fantastical. I don’t believe it’s credible. It sounds a little too much like what someone thinks a conservative prepper sounds like, a leftie attempt at playing conservative online media.

The Defense Department (not Al Gore! LOL) came up with the Internet, so if anyone can “jam” it in any way, you’d think it’d be the government.

I would guess nearly all the internet access there is by smartphone and that could easily be jammed. It isn’t legal to jam so that would be surprising if they did and could have significant repercussions.

Wired Internet could only be blocked at the service provider backhaul connections without extreme measures.

An localized internet blackout (IMO) could only be accomplished if the .gov is working in conjunction with local ISPs. For "last mile" providers like Comcast and AT&T...this COULD be relatively easy as you don't need "boots on the ground" from the providers to turn off service connections. A more detailed discussion of this quickly becomes "local" in the sense that retail customers of ISPs in that area are probably set up using various configurations of very small aperture terminals (VSATs) may also use satellite links to transport traffic to middle mile facilities or directly to the national backbone networks.

How they would go about blocking satellite access...is beyond my scope of knowledge. But my point is, a localized disruption is NOT entirely impossible.
