Solana faces slowdown in block production, network restarted By Cointelegraph

network faced a slowdown in block production on Fev. 25 following the upgrade in the validator software. The incident resulted in disruptions to transactions and led validators to downgrade the software in an attempt to restore network performance.

The technical issue started around 6:00 AM (UTC), leading validators to downgrade to version 1.13 in an effort to restore transactions in the network. The downgrade, however, was not enough to restore Solana to normal operations, forcing the decision to restart the network on v1.13.6.
