In 2051 a Neo-Luddite movement known as "Amos"/"The Adherents of Amos" detonated some sort of weapon in LEO (low earth orbit) causing a global black out shutting down technology and to a extent modern society. To Amos the snuffing out the sin and vice of technology that "corrupted" our souls is the only way to save humanity and bring about global equality (crash the economy to get rid of the rich poor divide). No matter though technology was restored eventually and things slowly pieced itself together.
Now what I'm stuck on is the device itself. What kind of device (delivered by rocket) could have the capacity to explode in orbit and shut down technology across the globe. Frying power networks, taking down servers corrupting data, etc.
The device has to: cause a global black out for the most part (a few exceptions are fine as long as the black out is still a global issue), the black out takes at least weeks preferably months to fix directly (as in restore power completely, recovery would take years), and finally not cause too much damage to the environment a little would be acceptable however.
Amos has deep pockets (backing from disenfranchised rich people/skilled person's turned fanatics as well as support by misinformed religious groups
Don't worry about the fate of Amos they fall apart due to this black out actually worsening the economic and social conditions of the world instead of solving much.
The device would preferably be delivered by ICBM/Related technology
