The Solana (SOL) network saw a seven-hour outage between April 30 and May 1. This was a result of a huge amount of transactions from the non-fungible token (NFT) minting bots.
The network saw an astounding 4 million transactions congesting the network, which caused validators to be knocked out of consensus. This resulted in Solana experiencing an outage from around 8 PM UTC on April 30. The network was successfully restarted at 3 AM on May 1.
After the incident, it was found that bots hoarded the Candy Machine application that is used by Solana NFT projects to launch collections. After this discovery, Metaplex announced that traffic from bots on the application was partially to blame for the network outage.
The most recent outage marks the seventh time this year that Solana has suffered outages, according to its own status reporting.
