Definition
The CLOUD Act (Clarifying Lawful Overseas Use of Data Act, 18 U.S.C. § 2713, signed into law March 23, 2018) is a United States federal statute that authorizes US courts to compel US-based electronic communication service providers and remote computing service providers to disclose data stored outside the United States in response to a valid US legal process — regardless of where the data physically resides.

Why it reversed prior precedent
Before the CLOUD Act, a 2016 Second Circuit Court of Appeals ruling had held that the US government could not compel Microsoft to produce emails stored on servers in Ireland. The CLOUD Act reversed that precedent at the statutory level: physical storage location is no longer a reliable shield if your service provider is headquartered in the United States, incorporated under US law, or delivers services through US entities. Major cloud hyperscalers — AWS, Azure, Google Cloud, and others — fall within the statute's reach regardless of which regional availability zone stores your data.
The sovereign response
For operators who evaluate the CLOUD Act as a material risk to their data strategy, the practical response mirrors the broader digital sovereignty playbook: choose providers whose legal domicile is outside US jurisdiction, or run infrastructure on hardware you control in a jurisdiction you have evaluated. Canadian digital sovereignty resources explore provider alternatives and local hosting paths. D-Central's open data hub publishes mining datasets under CC BY 4.0 with no cloud lock-in.
