Solana Shrugs Off Massive DDoS Attack as Network Performance Holds Steady

Solana successfully absorbed a massive 6 Tbps DDoS attack, one of the largest in internet history, with zero impact on block production or user-facing performance.
Network telemetry showed median transaction confirmations stayed around 450 milliseconds throughout the week-long campaign, highlighting significantly improved resilience since its 2022 outages.
The event drew sharp contrasts with the Sui network, which reportedly suffered block delays and performance degradation during a separate DDoS attack just days earlier.

Solana is experiencing a sustained distributed denial-of-service (DDoS) campaign (that no one noticed) and has peaked near 6 terabits per second, but monitoring shared by builders suggests normal user-facing performance has largely held.

Pipe Network described the traffic as “one of the largest in internet history,” estimating it at billions of packets per second. It said typical failure signals under this load (higher latency, missed slots, or slower confirmations) have not appeared in its telemetry. Pipe reported median transaction confirmation around 450 milliseconds, p90 under 700 milliseconds, and slot latency holding at 0–1 slots.

No Effect on Performance

Solana Labs co-founder and COO Raj Gokal echoed the claim that the attack has had “zero effect on performance.”

Helius CEO Mert Mumtaz said the campaign has been ongoing for at least a week and argued that resilience is not solved by validator count alone, claiming a smaller set of professionally run validators can be more DDoS-resistant than a much larger set run with weaker infrastructure.

The discussion followed commentary about Sui being DDoS’d and seeing delays, which was used to argue that low validator counts can reduce network resilience.

Solana co-founder Anatoly Yakovenko added that validator count can matter in specific leader handoff dynamics, because an attacker may need to sustain pressure across more of the network to reliably disrupt block production, raising the cost of disruption.

SolanaFloor summarised the episode as a week-long attack peaking near 6 Tbps with sub-second confirmations and stable slot latency, and contrasted it with reported degradation on Sui during a separate DDoS event. At the time cited, SOL traded at US$126 (AU$193).
