JAKARTA - On Saturday, February 25, 2023, Solana's smart contract platform experienced a significant technical impairment known as a "large branching event". This resulted in a transaction failure for some users, as well as a slowdown in block finalization.

Solblaze, liquid staking pool, reported that although Solana did not completely stop producing the block, the network experienced a slowdown as a result of the forking incident.

According to the Solana incident report, the issue is referred to as a "cluster instability". Solana also indicated that a coordinated restart had been launched to accelerate block finalization. The account states that the validators are working with Solana technicians to identify the cause of the problem and find the best solution.

"Coordinated restarts are being carried out to address issues during the update from 1.13 to 1.14 which caused the finalization of the block to slow down significantly," wrote Solana Status (@SolanaStatus), February 25, 2023.

The issue was confirmed by the Solana Status page which states that Solana engineers are investigating slow root production on beta mainnets.

Solana also provides a document link that gives validators instructions on how to resume restart. Validator is asked to take a snapshot in slot 179526408, modify the validator command line, install the previous version of 113.6, and then restart the validator.

This event reminds us of the problems blockchain faced last year, including some block production blackouts. Solana and the validators are working hard to fix this problem as quickly as possible and avoid a worse impact on users.
