Solana’s staking network suffered a major operational scare on August 12, 2026, when a routing failure at infrastructure provider Teraswitch temporarily knocked 28.83% of all staked SOL out of consensus. The disruption lasted approximately 33 minutes and affected roughly 90 validators, bringing the network dangerously close to the 33.34% threshold at which Solana would stop finalizing transactions.
According to Marinade Finance, the incident originated with autonomous system number AS20326, which held 118.9 million SOL, representing 27.34% of the network’s total staked SOL. About 94% of that stake went offline simultaneously. The affected validators missed a combined 333 SOL in staking rewards, though Marinade said operators would absorb the loss and stakers would have zero exposure.
Teraswitch reported that customers at sites including LON1, AMS1, AMS2, AMS3, DUB1, DUB2, FRA2, SGP1, SGP2, TYO1, TYO2 and TYO3 experienced loss of reachability. Engineers identified the malformed route within 10 minutes and removed MIA1 from the backbone, allowing affected sites to reconverge and restore service at 04:16:15 UTC.
Solana’s second-largest validator, Helius, was down for the entire 33-minute episode. Of 74 validators measured by Marinade, only three recovered cleanly: Solana Strategies’ laine, Cogent Crypto, and Lion3d.
The event did not break Solana’s uptime streak, which reached 30 months two days earlier. Solana’s official status page maintained a clean 100% cluster uptime for the previous 90 days. However, the near-miss highlighted concentration risks in staking infrastructure. Marinade Finance said it plans to review its concentration cap standards, and the incident is likely to intensify calls for stakers to diversify across validators and data centers.
At SOL’s trading price of roughly $76.9, the lost rewards were worth about $25,600 — a small sum that nearly translated into a network-wide halt. Solana’s last full network outage occurred on February 6, 2024, and lasted roughly five hours.
