An emp would be a wicked effective first strike because it will short or everything with an antenna and ADC based sensor. However basically everything not in that category is fine unless the emp was created with such intensity that it also kills people. Your average computer case makes an adequate Faraday cage for protecting the sift electronics inside. Laptops with plastic cases would be destroyed.

Most servers are inside a Faraday cafe to reduces interference and outside noise so the internet would likely survive though a lot of new network cards will be required... but the cell phone network would not.

The most major hit would actually be currency. With so much of currency being virtual and reliant on intercommunication losing telecom means noon physical currency losses value. Which means that the global currency does not balance.

Rebuild time for replacing network cards for the internet day a few months and millions of dollars. Replacing every cell phone antenna.. Tens of billions and will likely take a lot longer. Strife fom the loss of interindustry banking.. I don't know
