Solana Withstands 6 Tbps DDoS Attack With No Network Disruption

Solana revealed that its network has been under a sustained distributed denial-of-service attack for the past week. The scale was massive. At its peak, traffic reached nearly 6 terabits per second. That places the incident as the fourth-largest DDoS attack ever recorded across any distributed system. Despite the size, the outcome surprised many. 

Solana’s network kept running. Blocks continued to produce. Transactions confirmed in under a second. Slot times stayed steady. In short, users barely noticed. The team said this is not luck. It is designed. Solana has always aimed to stay live even under extreme stress. This week became a real-world stress test, and the network passed it.

No Downtime, No Slowdowns, No Drama

During the attack window, on-chain data showed normal activity. Validators stayed online. Applications kept working. Users sent transactions without delays. Solana stated clearly that network performance was not impacted. That matters because DDoS attacks usually aim to overwhelm systems until they fail. In this case, the attackers threw everything they had, and nothing broke.

For context, only a few attacks in history have crossed this traffic level. Google Cloud faced a 46 Tbps attack in 2022. Cloudflare customers saw attacks near 38 Tbps in 2024. Solana itself previously handled a 26 Tbps event in 2023. Now, this latest 6 Tbps attack adds another entry to that short and scary list. Yet again, Solana stayed online.

A Sharp Contrast With Other Networks

The timing made the contrast even clearer. Around the same period, the Sui network also faced a DDoS attack. That incident caused block production delays and periods of degraded performance. Solana avoided those issues entirely. Confirmations stayed fast. Latency stayed flat. From a user perspective, it was business as usual.

This difference highlights how network architecture matters. In particular, Solana’s design focuses on parallel processing, high throughput, and validator coordination. While those choices can look abstract on paper, consequently, they become very real under attack. In moments like this, resilience matters more than hype. Networks do not get credit for surviving quiet days. They earn it when chaos hits.

Why This Moment Matters for Solana’s Long-Term Story

Security and uptime have been long-running talking points around Solana. Specifically, critics often point to past outages, while supporters argue the network keeps improving. In light of this, this event adds real data to that debate. Handling one of the largest DDoS attacks ever recorded without disruption sends a strong signal. Moreover, it shows progress, as well as learning, and it further shows that Solana can operate under pressure.

For developers, this builds confidence. For institutions, it reduces risk concerns. Also, for users, it simply means things work when they tap “send.” The Solana team summed it up best. One of the network’s core goals is to keep running, even when attacked. This week, that goal was not theoretical. Instead, it was proven live, on-chain, and at full scale. Indeed, in crypto, that kind of resilience is not just nice to have; rather, it is everything.
