Solana has weathered one of the most powerful distributed denial-of-service (DDoS) attacks ever recorded without any visible impact on network performance. According to data shared by SolanaFloor, the network has been under a sustained attack for over a week, with traffic peaking at nearly 6 terabits per second (Tbps). This ranks as the fourth-largest DDoS attack in internet history.
Despite the massive scale of the assault, network metrics showed Solana continued to process transactions normally, with sub-second confirmations and stable slot latency throughout the period. Validators and core infrastructure absorbed the traffic without degraded performance. Charts accompanying the disclosure place the Solana incident alongside historic attacks targeting major centralized infrastructure providers like Google Cloud, Cloudflare, Microsoft Azure, and AWS, marking a rare case of a public blockchain facing traffic volumes comparable to the largest assaults on traditional internet services.
The timing of Solana's resilience is highlighted by a contrasting event. Just a day earlier, the Sui network experienced a DDoS attack which resulted in delayed block production and periods of reduced performance. This sharp contrast underscores the significance of Solana's architectural maturity, which has been a point of focus since earlier congestion episodes.
While the network proved its robustness, on-chain data points to other challenges for Solana. Glassnode data shows the network’s 30-day realized profit-to-loss ratio has remained below 1 since mid-November, a level typically linked to bearish conditions. Analysts at Altcoin Vector describe the situation as a “full liquidity reset,” a phase that has historically marked the early stages of new liquidity cycles.
