## Upcoming Network Upgrade
On 16 January 2019, a decision was taken to postpone the upgrade of the Ethereum Network, the upgrade named “Constantinople”, scheduled to complete on 17 December 2019.

The next network upgrade "Constantinople 2" is targeted at **27 February 2019**, block number **7.280.000**.
The next network upgrade "Constantinople 2" (also called "Petersburg") is targeted at **27 February 2019**, block number **7.280.000**. Technically, both Constantinople 1 and 2 are activated at the same block, where Contstantinople 1 will activate all EIPs and Constantinople 2 will deactivate EIP 1283 immediately due to [security concerns](https://blog.ethereum.org/2019/01/15/security-alert-ethereum-constantinople-postponement/).
