A routing failure at a major data-center provider knocked almost 29% of Solana's staked tokens offline Wednesday morning, according to Marinade Finance's incident account. Solana continued finalizing transactions, but the network came within about 20 million SOL of the one-third delinquency threshold that would have stopped finality.
About 90 validators were affected and lost a combined 333 SOL in rewards. Marinade said its validator-bond system will cover those losses. The much larger risk was not missed rewards: once more than one-third of stake is offline, the remaining validators cannot produce the supermajority needed to finalize blocks.
The network stayed live, but the margin was thin
The failure was traced to a bad internet route originating at Teraswitch, not to a Solana consensus bug. That distinction does not remove the concentration risk. Many independently operated validators can still share one provider or network path, allowing one infrastructure fault to remove a large block of stake at the same time.
Solana suffered a roughly five-hour outage in February 2024 after a different fault. Wednesday's event did not become a halt, and the validator losses were limited. The operational question now is whether stake and hosting are distributed widely enough that another provider failure cannot cross the finality threshold.
