[Canton] - Devnet Network-Wide Topology Freeze (Upstream Event)

Scheduled for Oct 29, 13:00 UTC - Oct 30, 13:00 UTC

Scheduled

The Canton network is applying a topology freeze on DevNet in preparation for the Logical Synchronizer Upgrade (LSU). This is a network-wide event coordinated by the Canton Foundation, not Blockdaemon maintenance.

Window: Oct 29 2026, 13:00 UTC to Oct 30, 2026, 13:00 UTC (until after the LSU completes; may extend slightly)

Impact:
Transactions continue to work normally.
Topology-changing operations will not succeed during the window, including new contract deployments, validator onboarding, and DAR uploads.
Action required: None. Customers should schedule any topology-changing operations outside this window. We'll update this notice when the freeze is lifted.

If you have any questions or concerns please reach out to your account managers.
