I recently read that many businesses in the EU fear the U.S. administration could activate a so-called "U.S. kill switch," cutting them off from essential services and potentially stopping their operations within a day or two. How could that actually work if a company uses European email providers, cloud infrastructure, and other local services? Is this a realistic risk or mostly fearmongering?

There isn’t one physical kill switch for the internet. The concern is that European organizations often depend on American companies such as Microsoft, Google, Amazon, and Apple. Those providers could restrict an account or service because of U.S. sanctions, export controls, or other legal requirements. That could be extremely disruptive if a business relies on one provider for email, identity management, files, or cloud hosting.
Claims about a switch hidden somewhere in the eastern United States are misinformation. The U.S. does not control the whole internet or all top-level domains, and internet traffic does not normally pass through one central American system. European networks can keep operating independently, but companies may still face problems if their particular vendors are subject to U.S. jurisdiction or if they rely on American technology.
Using European email or cloud storage helps, but it is important to check who owns the provider, where its infrastructure is located, and whether it relies on American subcontractors.
So the headline is exaggerated, but the underlying dependency is worth taking seriously. Businesses can reduce the risk with local or self-hosted services, regular offline backups, multiple suppliers, and tested recovery plans. Switching providers is not always quick, especially when a company depends on proprietary software and centralized identity systems.
The risk is more like losing access to an account than the entire internet being switched off. If a company stores its documents in a major hosted service and that provider suspends the account, employees might suddenly lose email, files, calendars, and applications. A prominent example involved Microsoft restricting access to an international official’s work account because of U.S. legal obligations. That shows the possibility is real, although it doesn’t mean every European business could be shut down instantly.
The practical defense is keeping independent backups, having alternative providers, and avoiding a single U.S.-based platform for every critical function.
Even organizations that appear to be using European services may still depend on American software, cloud infrastructure, payment systems, certificates, or identity providers somewhere in the chain.
