Solana survives massive 6 Tbps DDoS with minimal impact — Yakovenko calls Solana’s DDoS resilience a bullish signal

Solana co-founder Anatoly Yakovenko and several sources close to the Solana ecosystem stated that the network has faced an industrial-scale DDoS attack—one of the largest ever recorded—which nevertheless had almost no impact on its performance.

Yakovenko first reported the 6 Tbps DDoS attack against Solana in a post on X on December 9, calling it a “positive signal.”

“Someone is spending as much money sending data to the blockchain as the blockchain is earning,” Yakovenko said.

Earlier this week, Solana Labs co-founder and president Raj Gokal suggested that the attack may still be ongoing. David Rhodus, CEO of decentralized physical infrastructure (DePIN) project Pipe Network, added that the ongoing DDoS attack against @solana is among the largest in internet history.

But we saved everything 🙂.

“A volumetric attack of 6 Tbps means billions of packets per second. Under this load, one would normally expect increased latency, skipped slots, or delayed confirmations.
Instead, the data shows median transaction confirmation time of ~450 ms, p90 under 700 ms, and slot delay remaining at 0–1 slots,” Pipe Network stated.

A chart published by Pipe Network shows that Solana experienced the fourth-largest DDoS attack ever recorded. However, as Cointelegraph notes, in 2025 alone Cloudflare reported a 29.7 Tbps attack, KrebsOnSecurity reported a 6.3 Tbps attack, and Gcore reported a 6 Tbps attack—none of which appear on Pipe Network’s chart.

Why the focus on DDoS attacks matters

Solana has a history of multiple network outages, some of which were linked to DDoS-style events. However, in recent years the network has made significant progress toward greater resilience—something Yakovenko has sought to emphasize. Since 2020, there has not been a single year in which Solana did not experience an outage for some reason.

In December 2020, a block propagation bug halted the network.
In September 2021, Solana’s mainnet suffered a 17-hour outage when the launch of Grape Protocol’s IDO on Raydium’s AcceleRaytor overwhelmed the network in a DDoS-like event.
In 2022, Solana experienced three separate outages: a seven-hour outage caused by transaction spam from bot accounts, a four-and-a-half-hour outage due to a consensus failure bug, and an 8.5-hour outage caused by a fork selection rule error that also led to consensus failure.
In late February 2023, a bug in Solana’s deduplication logic resulted in nearly 19 hours of downtime.
In 2024, the network suffered only one outage, lasting almost five hours, caused by a bug that triggered an infinite recompilation loop.

This year, however, appears to be the first time Solana may finish without a single outage—something Yakovenko considers a “bullish factor.”
