Hello node operators, Flow Mainnet will be sporking on **2022-08-24 08:00am PT/ 3:00 pm UTC** going from Mainnet-18 to **Mainnet-19**. The Flow access nodes will be turned off during that time. Once the spork is complete, at around **9:30 AM PT** , a message will be posted on the [message forum](http://forum.flow.com/c/mainnet-sporks) and on Discord requesting you to start your nodes. Please make sure you have subscribed for updates on [http://forum.flow.com/c/mainnet-sporks](http://forum.flow.com/c/mainnet-sporks) or have joined the Discord `#flow-validators` channel.
