The US, on the other hand, recently enacted the CLOUD Act (PDF). And based on how it works, it might make it easier for foreign authorities (like British law enforcement) to compel US-based companies to hand over data for investigations. Google is based in Ireland in the EU, along with many other tech companies like Facebook. Reuters says the tech giant decided to move British users out of Irish jurisdiction, because it remains unclear if Britain intends to adopt the GDPR following its exit from the European Union.
We've asked Google for a statement and a confirmation. If Reuters' report is true, though, then users in the UK will be required to acknowledge Google's new terms of service, along with the new jurisdiction in the near future.
Update 02/20/20 9PM ET: A Google spokesperson told Engadget:
"Like many companies, we have to prepare for Brexit. Nothing about our services or our approach to privacy will change, including how we collect or process data, and how we respond to law enforcement demands for users' information. The protections of the UK GDPR will still apply to these users."
