[Canton] - Mainnet Topology Freeze

Incident Report for Blockdaemon

Identified

We would like to inform customers that Canton Mainnet is currently under a Topology Freeze as part of an upstream Canton synchronizer upgrade. This is not a Blockdaemon-initiated change.

The freeze began Friday, June 26 at 13:00 UTC and is expected to conclude just after 13:00 UTC on Saturday, June 27. During this period, topology changes are temporarily disabled. Customers attempting such operations may receive errors indicating the network is frozen. All other operations, including normal transaction processing, continue to function as expected.

We are monitoring the situation closely and will provide further updates as they become available. If you have any questions or concerns please reach out to your Customer Success Manager.
