Solana Network Avoids Critical Failure After TeraSwitch Outage

The Solana network narrowly avoided halting finalization on August 12 due to an outage at TeraSwitch, one of its key infrastructure providers.

An incorrect routing issue led to a loss of connectivity for 12 sites across London, Amsterdam, Dublin, Frankfurt, Singapore, and Tokyo, affecting about 28.83% of staked Solana coins and causing 333 SOL in rewards to be lost for the affected validators.

The critical threshold for losing finalization is 33.34%, but the network was able to recover after 33 minutes when TeraSwitch disconnected its MIA1 site from its internal backbone network.
