After seven hours of downtime the Solana validators were able to restart the proof-of stake blockchain network, according an an updateToday, May 1, 2009.
“Validator operators successfully completed a cluster restart of Mainnet Beta at 3:00 AM UTC, following a roughly 7 hour outage after the network failed to reach consensus. Network operators and dapps will continue to restore client services over the next several hours.”

Twitter shared details that Solana was taken offline Saturday at 20:00 UTC by bots who flooded it with 4,000,000 transactions per second, and 100gbps transaction data.
These transactions were largely connected to the Metaplex Candy Machine NFT program, which most new Solana projects use for minting NFTs.
Due to such a high demand on the network validators couldn’t reach consensus. This led to block production being stopped.
Solana validators did not coordinate a restart until seven hours later. using instructions from one of the network’s validators. The restart, handled via Solana’s discord channels and the Google doc instructions, saw validators finally take control at slot 131973970.
