Overview
- An AWS failure in Northern Virginia tied to DynamoDB and DNS temporarily knocked some Signal users offline, according to the company.
- Elon Musk said he no longer trusts Signal and promoted X Chat, later asserting that X messages are fully encrypted with no AWS dependencies or advertising hooks.
- Signal’s president defended the app’s end-to-end encryption model and noted that Signal does not hold users’ encryption keys.
- X labels X Chat as beta and it is not open source, limiting third‑party audits, while security researchers emphasize the need for open code and verifiable builds for trust.
- Developers flagged longstanding reproducible‑build gaps for Signal’s Android app and noted app‑store distribution makes independently matching deployed code to published source more difficult.
