The mechanism

18 USC §2713 reads: "A provider of electronic communication service or remote computing service shall comply with the obligations of this chapter to preserve, backup, or disclose the contents of a wire or electronic communication and any record or other information pertaining to a customer or subscriber within such provider's possession, custody, or control, regardless of whether such communication, record, or other information is located within or outside of the United States."

The operative phrases — "possession, custody, or control" and "regardless of whether…located within or outside" — make the extraterritorial reach explicit.

Who can be served

Any US-incorporated provider. Any US subsidiary of a foreign provider where the subsidiary has operational control. Any non-US provider with sufficient US presence (the "purposeful availment" test). In practice this includes every major cloud platform: AWS, Azure, GCP, Cloudflare, Akamai, Backblaze, Dropbox, OneDrive, GitHub.

Why hyperscaler regional storage doesn't solve it

A bucket in Frankfurt operated by AWS EMEA is still reachable by a US National Security Letter served on AWS Inc. The corporate group, not the regional subsidiary, holds "possession, custody, or control" in the §2713 sense. EU residency clauses don't change this.

What customer-managed keys do and don't do

Keys in the provider's KMS — even "customer-managed" — are operationally reachable by the provider's compute plane during reads. A court can compel that plane to perform the unwrap. CMK reduces but does not eliminate CLOUD Act exposure.

The architectural answer

For sovereignty against the CLOUD Act to be architectural rather than contractual, three things must hold: keys derived only on the customer device; data spread across multiple providers in multiple jurisdictions; no server-side API path returning plaintext. SkyeConnex enforces all three. Read the full mechanic →
