We will perform a firewall migration to improve security, performance and reliability of our service on 2026-03-24 at 22:00 CET.

- Date: 2026-03-24 - Time: From 22:00 CET to 00:00 CET (2 hours) - Expected Impact: During this period all services will be temporarily unavailable on both V2 and V3.
To improve infrastructure resilience and scalability, new IP address ranges are being added to the Yousign platform.
Are you affected?
This update concerns organizations applying strict network security policies, specifically: - Incoming Traffic (Webhooks): If servers only accept requests from known IP addresses. - Outgoing Traffic (Corporate Firewall): If the internal network restricts outbound connections to specific IPs rather than domains.
