The Canton network is applying a topology freeze on Mainnet in preparation for the Logical Synchronizer Upgrade (LSU). This is a network-wide event coordinated by the Canton Foundation, not Blockdaemon maintenance.
Window: November 06, 2026, 15:00 UTC to November 07, 2026, 15:00 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.
