Solana, Arbitrum One and Nethermind Had a Really Bad Day Due to Technical Issues

September 14 turned out to be a very unfortunate day for three networks at once. Solana, Arbitrum One and Nethermind faced unforeseen technical problems.

At 12:38 UTC on Tuesday, September 14, Solana Status reported that the beta version of the Solana mainnet was intermittently unstable for 45 minutes.

Six hours later, Solana Status explained that the instability was caused by network congestion due to an increase in transaction load of up to 400,000 per second. This resulted in a denial of service and caused the network to fork.

Since the Solana network could not be stabilized, the decision was made to restart it. At the moment, a new release is being prepared, with additional information coming later.

Such an unpleasant event expectedly affected the SOL rate. In just 12 hours, the price dropped by 15%. Before the incident, SOL was trading at $175, but after the news of technical problems and the restart of the network, the token soared to $145.

On the same day, the Ethereum layer-two roll-up network Arbitrum One faced similar problems. Tech support reported that the network’s sequencer went offline for about 45 minutes after too many transactions were sent to it in a short period of time. And, since the network is still in the testing stage, similar failures are possible in the near future.

But the troubles in the crypto world did not end there either. Developer Marius Van der Weyden reported that on September 14, an unknown organization tried to hack into the Nethermind network.

Several Nethermind nodes were tricked into an invalid chain, he said. All the other clients “rejected the long sidechain as invalid”. Since then, all the affected nodes have been reorganized back into the correct chain.

Nethermind later reported that the affected archive nodes were restored and most of the fast sync nodes were unaffected. However, one of the fast sync nodes could not be reorganized due to shrinking. In addition, the team assured that they had taken measures to prevent such attacks.
