According to CoinMeta, on August 12th, Solana approached a critical threshold due to routing failures, resulting in 28.76% of the pledged SOL entering an invalid state. Based on the analysis of Marinade Finance's reconstruction, at its worst, only 19.9 million SOL were left to separate the network from the one-third pledge threshold. This incident demonstrates that although the network was still running, some validators lost their voting capability due to routing issues, affecting the network's normal consensus. This event reminds us that the true redundancy of a network depends not only on the number of validators and the distribution of pledges but also on the concentration of hosting and routing paths.
