The Ethereum (ETH) Base layer 2 network, owned by the Coinbase exchange, was down for 20 minutes on September 21 and did not produce any blocks.  This was the second base outage since its launch.  Bass producer Jesse Pollak confirmed the event.  Notably, the event received little news coverage compared to similar outages on networks such as Solana (SOL).  Base is one of Ethereum's most popular Layer 2, and this outage could raise concerns about its reliability.  However, the base team was praised for their quick response and technical skill in fixing the problem.
