Solana Network Survives Teraswitch Routing Failure

A recent Teraswitch routing failure knocked nearly 29% of Solana's stake offline, but the network continued to produce blocks.

The incident on August 12 was caused by a stale default route left on a Miami edge router, which prevented affected data centers from reaching the Internet through healthy local routers. Twelve sites across Europe and Asia-Pacific lost Internet and inter-site connectivity, including infrastructure hosting Solana validator and RPC nodes.

Metrika's observer recorded about half an hour in which newly produced blocks had not yet reached finality, the point at which their transactions become irreversible. The backlog finalized as connectivity returned.
