Hello **Consensus** and **Collection** Node Operators,

Transaction fees have increased on Flow. Please see the announcement here:  
[https://forum.flow.com/t/upcoming-mainnet-update-transaction-fee-changes-going-live-on-monday-dec-8th/8427/2](https://forum.flow.com/t/upcoming-mainnet-update-transaction-fee-changes-going-live-on-monday-dec-8th/8427/2)

To ensure uninterrupted operation, **please fund the machine accounts associated with your Consensus and Collection nodes as soon as possible, with at least 2 FLOW**. _The machine account is different from your staking account_. You can read more about machine accounts [here](https://developers.flow.com/protocol/staking/machine-account).  
With the updated fees, transactions submitted by these nodes will cost more, causing machine accounts to deplete faster.

You can find your machine account address in the file:

`bootstrap/private-root-information/private-node-<your-node-id>/node-machine-account-info.priv.json`

Example:

```auto
cat /var/flow/bootstrap/private-root-information/private-node-info_8adde2ecac9416bea12940c5a376abf5bc043fed5c5983be4abd3dab4248cdf2/node-machine-account-info.priv.json
{
"Address": "0xf81465e23090eb86",
…
…
}

```

You can check the balance on [flowscan.io](https://www.flowscan.io/account) or through flow cli (`flow accounts get <access address>` -n mainnet)

**Deadline: Please complete these updates by Tuesday, Dec 8th EOD in time for epoch transition on Wednesday, Dec 9th.**

Additionally, please update your alerting thresholds as follows:

Collection:

- Minimum: 0.25 FLOW
- Recommended: 0.75 FLOW

Consensus

- Minimum: 2 FLOW
- Recommended: 6 FLOW

If you have not setup monitoring for machine account balance, please see the earlier [announcement](https://forum.flow.com/t/collection-and-consensus-node-operators-machine-account-balance/2654) and set it up now. Please ensure that you alert on both,

```auto
machine_account_balance < machine_account_recommended_min_balance

```

and

```auto
machine_account_is_misconfigured > 0

```

No action required for other node types.

Thank you,  
Flow Team
