Solana nearly froze as a single routing error took 29% of the network stake offline
The newly detailed Teraswitch failure stayed below Solana’s finality-halt threshold, while independent telemetry showed delayed finality and sharply lower throughput.
The Solana network kept producing blocks on Aug. 12 when an infrastructure failure stopped validators representing nearly 29% of network stake from voting, according to a Solana Foundation account published Sept. 14.
Independent monitoring found thatthe chain remainedlive, yet its performance deteriorated: more leader slots were skipped, transaction throughput fell sharply, and settlement finality was delayed.
The disruption began at Teraswitch, which the Foundation described as Solana’s largest infrastructure provider. ATeraswitch postmortemtraced the outage to a stale default route left on a Miami edge router, with Teraswitch's provider traffic fully recovering 33 minutes after the first alarm.
Routine transit-provider maintenance activated that route, while transposed values in a routing policy applied a “no-export” instruction toward Europe and Asia-Pacific.
In practical terms, the bad route spread across Teraswitch’s network and 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 validatorand RPC nodes.
Independent 블록체인-risk monitoring firm Metrika broadly corroborated both the scale of the disruptionand continuous block production. Its data showed skipped slots rising above 32% and non-vote transaction throughput dropping below 300 per second from a typical range of roughly 1, 100 to 1, 300.
Metrika’s observer also 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.
Solana avoided a chain-wide production halt, but users and systems depending on rapid settlement faced materially weaker performance.
