Locally a great amount of work has been completed to bury utilities, Fiber for communications should be safe.
I know there is scripture for "the passages will be stopped" with an interpretation of the word "passages" meaning communication means.

Everything is connected. If the power goes out and laptop and phone are fried, doesn't matter if some cables still work.
The power grid is like dominoes, you don't have to knock them all down, knock a few down and the rest fall. Knock out the grid in NYC and you probably take the entire NE down. Knock out the grid in NY State and you probably take the whole East coast down.
Also all these cars and trucks are now equipped with chips. If they get fried by an EMP there won't be any deliveries which means no new parts to repair the things that got fried.
Also, consider gas stations, if your pump is fried you can't pump gas. So the gas stations don't have gas because the trucks got fried and even if a truck isn't fried it can't deliver gas because the pumps at the gas station don't work.
But suppose somehow that half the trucks can get up and running, even if they have to carry their gas with them. By this time you will have looting and roving gangs, being a truck driver will be way too dangerous, at least in any cities.
If we actually do get attacked by Russia it will almost certainly include these mega Tsunamis they can create which will wipe out the entire coastline 5 miles in. That means all ports are wiped out, all imports are wiped out. So forget anything that must be imported. So you can't buy a new phone or a new laptop or a new car. Do you realize there aren't any cars that are 100% made in America?
Also when this hits the cars and trucks will all get fried, which includes cars and trucks in the middle of the road. It will become a chaotic mess.
