Solana has been operating under a sustained distributed denial-of-service (DDoS) attack for the past week, according to information shared by SolanaFloor. The attack peaked near 6 terabits per second (Tbps), ranking as the fourth-largest DDoS attack ever recorded against any distributed system.
Despite the scale of the attack, network data indicates that Solana’s performance remained unaffected throughout the period.
Network Performance Remains Stable Despite Attack
According to the update, Solana continued to process transactions with sub-second confirmations and stable slot latencyduring the attack window. No degradation in network performance was observed, even as traffic volumes reached levels comparable to historic DDoS events affecting major global infrastructure providers.

The sustained nature of the attack, combined with the absence of visible disruption, highlights the network’s ability to maintain operational stability under extreme conditions.
Attack Ranks Among Largest In History
A comparative chart included in the update places Solana’s 2025 attack alongside the largest DDoS incidents ever recorded. While the attack falls below historic peaks seen by Google Cloud and Cloudflare customers, it exceeds several well-known incidents involving Microsoft Azure, AWS, GitHub, and Dyn DNS.
At approximately 6 Tbps, the Solana attack stands out as the largest DDoS event recorded against a blockchain network shown in the comparison.
Sui Network Also Impacted By DDoS Activity
The update also notes that the Sui network was targeted by a DDoS attack one day prior. Unlike Solana, the Sui incident resulted in delays in block production and periods of degraded network performance, indicating a measurable operational impact.
The contrast between the two events highlights differing outcomes under similar attack conditions.
DDoS Activity Draws Attention To Network Resilience
The scale and duration of the attack place Solana’s recent experience among the most significant stress events recorded for distributed systems. With network metrics showing no disruption, the incident adds a notable data point to ongoing discussions around blockchain infrastructure resilience under sustained external pressure.
