What is a Warrant Canary?
A signed statement asserting we have received no secret order, national security letter, or hidden disclosure order. If it stops being updated, consider the service potentially compromised.
Limits and sovereignty
The canary is signed automatically by our sovereign GPG infrastructure. It does not replace an audit, but provides a traceable, dated and independently verifiable integrity signal.
