The Istanbul Hard Fork for Ethereum is ahead of schedule and causes technical hazards

The Istanbul Hard Fork for Ethereum is ahead of schedule and causes technical hazards.
It’s good to be ahead of Ethereum’s planned updates for the Istanbul hard fork and the testnet Ropsten, but that seems to have surprised some developers who were not ready.
In an article, we mentioned the dates of the future updates for the Ethereum blockchain with the hard fork Istanbul and testnet Ropsten, Rinkeby and Görli that are planned soon.
Ropsten: 6485846, due on October 2, 2019.
Rinkeby: 5435345, scheduled for November 13, 2019.
Görli: 1561651, due on October 30, 2019.
The testnet Ropsten is therefore ahead of schedule and this has caused technical problems but nothing really important if we believe the messages of the Ethereum developer team.
The Ethereum testnet network, Ropsten, was split into two chins after the activation of the testnet, Istanbul.
Problems reported by Hudson Jameson, Ethereum Foundation Community Manager:
Looks like there is an issue with the Ropsten Ethereum testnet after it hit the #Istanbul block. This is what testnets are for! Be aware that Ropsten will be unstable until this all plays out.

As Hudson Jameson says:
“That’s what testnets are for! Be aware that Ropsten will be unstable until this all plays out. ”
Scheduled to activate Ropsten on October 2 at block 6,485,846, Istanbul started two days ahead of schedule on September 30, 2019.
Ethereum developers explain that this event is due to an exceptionally fast block confirmation time.
On a blockchain using proof of work (pow) like Ethereum, miners and developers must update the software manually to ensure the continuity of the chain.
According to Hudson Jameson, the majority of the miners in the Ropsten blockchain testnet have not upgraded to the latest software version, the premature start of the hard fork Istanbul has surprised many developers.
This resulted in a splitting of the test network between the miners of the new Ropsten testnet and those remaining on the old blockchain.
The hardest in a hard fork on a blockchain proof of work (pow) is to synchronize all the minors on the blockchain so that they switch their software at the right time to a specific block number.
Jameson said:
“Right now, we are trying to get minors to get Ropsten on the good chain of Istanbul.”
Predictable technical hazards that are resolved by ensuring the proper synchronization of Ethereum miners, which involves especially effective communication with the community of developers on this blockchain that must absolutely increase capacity and validate these essential updates.
The blockchain Ethereum is full said Vitalik Buterin who explained the importance of the futures updates for this leading blockchain.
