Hello Flow **Access** , **Execution** and **Verification** Node Operators,

There will be a height coordinated upgrade on Flow mainnet tomorrow June 13th, Thursday at 3:00 PM UTC.

Please be prepared to update your Flow Verification, Execution and Access node(s) at that time.

**Actions needed from your side on June 13th:**

- For the **Verification** and **Execution** node, please update your docker to the new tag that will be provided that day as part of an announcement and restart the node.

Do **not** delete the data folder.

_Please complete this action within 24 hour of the announcement for the verification node_  
_If you are running multiple verification nodes, please restart the nodes one after the other (instead of all at once)._  
_Please complete this action immediately for the execution node_

This is **NOT** a spork, and the network will keep running during the upgrade.

Thank you for your cooperation,  
Flow Team.

hello Node operators,

Flow mainnet ran into some issues before the HCU.

There will be another HCU at 11:30 AM Pacific (18:30 UTC).

Please be ready to update your nodes after the HCU.

Thank you
