Solana co-founder Anatoly Yakovenko and several accounts tied to the network’s ecosystem said this week that Solana had been hit by a large distributed denial-of-service attack, with some posts citing traffic that peaked near six terabits per second (Tbps).
<a href="https://cointelegraph.com/learn/articles/anatoly-yakovenko" rel="" target="_self" title="https://cointelegraph.com/learn/articles/anatoly-yakovenko">Yakovenko</a> wrote in a Dec. 9 X <a href="https://x.com/aeyakovenko/status/1998331945260847558" rel="nofollow noopener" target="_blank" title="https://x.com/aeyakovenko/status/1998331945260847558">post</a> that Solana was under a six Tbps <a href="https://cointelegraph.com/explained/ddos-attacks-in-blockchain-networks-explained" rel="" target="_self" title="https://cointelegraph.com/explained/ddos-attacks-in-blockchain-networks-explained">distributed denial-of-service (DDoS) attack</a>. Earlier on Tuesday, Solana Labs co-founder and president Raj Gokal <a href="https://x.com/rajgokal/status/2000634127859720218" rel="nofollow noopener" target="_blank" title="https://x.com/rajgokal/status/2000634127859720218">suggested</a> the attack was still ongoing. Cointelegraph was unable to independently verify the attack or its scale.
Also on Tuesday, the CEO of Solana-based decentralized physical infrastructure network (DePIN) project Pipe Network, David Rhodus, <a href="https://x.com/DavidRhodus/status/2000753329841037552" rel="nofollow noopener" target="_blank" title="https://x.com/DavidRhodus/status/2000753329841037552">pointed out</a> that the shared metric put the attack at an “industrial-scale.” In an <a href="https://x.com/pipenetwork/status/2000812111929221500" rel="nofollow noopener" target="_blank" title="https://x.com/pipenetwork/status/2000812111929221500">update</a>, Pipe Petwork also claimed that the attack was “one of the largest in internet history,” as six Tbps “translates to billions of packets per second.”

A DDoS attack involves many devices flooding a target with traffic to overwhelm it and knock it offline or slow it down. A chart shared by Pipe Network suggested that Solana has faced the fourth-largest DDoS attack ever reported. Still, in 2025 alone, Cloudflare <a href="https://blog.cloudflare.com/ddos-threat-report-2025-q3/" rel="nofollow noopener" target="_blank" title="https://blog.cloudflare.com/ddos-threat-report-2025-q3/">reported</a> a 29.7 Tbps attack, KrebsOnSecurity reported a <a href="https://krebsonsecurity.com/2025/05/krebsonsecurity-hit-with-near-record-6-3-tbps-ddos/" rel="nofollow noopener" target="_blank" title="https://krebsonsecurity.com/2025/05/krebsonsecurity-hit-with-near-record-6-3-tbps-ddos/">6.3 Tbps</a> attack, and Gcore <a href="https://gcore.com/blog/ddos-6tbps-attack" rel="nofollow noopener" target="_blank" title="https://gcore.com/blog/ddos-6tbps-attack">disclosed</a> a six Tbps attack, with none appearing on Pipe Network’s chart.
Yakovenko <a href="https://x.com/aeyakovenko/status/1998331945260847558" rel="nofollow noopener" target="_blank" title="https://x.com/aeyakovenko/status/1998331945260847558">wrote</a> in a Dec. 9 post that the attack was “bullish,” also suggesting that “someone is spending as much as the chain makes in revenue to send it.” Similarly, Pipe Network highlighted that “under that kind of load, you’d normally expect rising latency, missed slots, or confirmation delays,” while the network was not showing any significant signs of stress.

<h2 id="solana-outage-history-and-fixes">Solana outage history and fixes</h2>
Solana has a history of multiple downtimes, some of which were tied to DDoS-like causes. In December 2020, a block propagation bug <a href="https://cointelegraph.com/news/following-six-hour-outage-solana-draws-criticism-and-support" rel="" target="_self" title="https://cointelegraph.com/news/following-six-hour-outage-solana-draws-criticism-and-support">halted the network operation</a>. Back in September 2021, Solana’s mainnet saw <a href="https://cointelegraph.com/news/scalability-or-stability-solana-network-outages-show-work-still-needed" rel="" target="_self" title="https://cointelegraph.com/news/scalability-or-stability-solana-network-outages-show-work-still-needed">a 17-hour downtime</a> as Grape Protocol’s launch of its onchain initial DEX offering (IDO) on the crowdfunding platform Raydium AcceleRaytor <a href="https://cointelegraph.com/news/solana-attributes-major-outage-to-denial-of-service-attack-targeting-dex-offering" rel="" target="_self" title="https://cointelegraph.com/news/solana-attributes-major-outage-to-denial-of-service-attack-targeting-dex-offering">overwhelmed the network</a>, much like a DDoS would.
In 2022, Solana saw three downtime instances. First, it experienced seven hours of <a href="https://cointelegraph.com/news/solana-suffers-7th-outage-in-2022-as-bots-invade-the-network" rel="" target="_self" title="https://cointelegraph.com/news/solana-suffers-7th-outage-in-2022-as-bots-invade-the-network">downtime due to transaction spam</a> from bot accounts, then the network <a href="https://www.helius.dev/blog/solana-transactions" rel="nofollow noopener" target="_blank" title="https://www.helius.dev/blog/solana-transactions">saw</a> four and a half hours of <a href="https://cointelegraph.com/news/solana-developers-tackle-bugs-hoping-to-prevent-further-outages" rel="" target="_self" title="https://cointelegraph.com/news/solana-developers-tackle-bugs-hoping-to-prevent-further-outages">downtime due to a bug</a> that caused a consensus failure. Again in 2022, Solana <a href="https://solana.com/news/09-30-22-solana-mainnet-beta-outage-report" rel="nofollow noopener" target="_blank" title="https://solana.com/news/09-30-22-solana-mainnet-beta-outage-report">experienced</a> 8.5 hours of downtime due to a bug in the fork choice rules, resulting in consensus failure.
This is where the network stability seemed to pick up slightly. Cointelegraph was able to locate only <a href="https://cointelegraph.com/news/solana-outage-triggers-ballistic-reaction-from-the-crypto-community" rel="" target="_self" title="https://cointelegraph.com/news/solana-outage-triggers-ballistic-reaction-from-the-crypto-community">one instance of downtime in 2023</a>, when, in late February, a fault in Solana’s deduplication logic led to almost 19 hours of downtime. In 2024, the network again saw only one downtime instance when it <a href="https://cointelegraph.com/news/solana-outage-client-diversity-beta" rel="" target="_self" title="https://cointelegraph.com/news/solana-outage-client-diversity-beta">went down for nearly five hours</a> due to a bug causing an infinite recompile loop.

Despite the clear downtrend, this is a lot of downtime for blockchain standards. Bitcoin (<a href="/bitcoin-price">BTC</a>), the world’s first blockchain, currently <a href="https://bitbo.io/uptime" rel="nofollow noopener" target="_blank" title="https://bitbo.io/uptime">has</a> an uptime of over 99.99%, with the last downtime incident taking place in 2013.
Bitcoin has seen only two downtime <a href="https://bitbo.io/calendar/downtime/" rel="nofollow noopener" target="_blank" title="https://bitbo.io/calendar/downtime/">incidents</a> since its first block was mined in January 2009. The first one took place in August 2010, when a value-overflow bug was exploited, briefly <a href="https://en.bitcoin.it/wiki/Value_overflow_incident" rel="nofollow noopener" target="_blank" title="https://en.bitcoin.it/wiki/Value_overflow_incident">creating</a> nearly 184.47 billion BTC until a patch reversed the issue. The second was in March 2013, when a bug <a href="https://bitcoin.org/en/alert/2013-03-11-chain-fork" rel="nofollow noopener" target="_blank" title="https://bitcoin.org/en/alert/2013-03-11-chain-fork">split</a> the network between Bitcoin Core 0.7 and 0.8. The 2013 event did not create new Bitcoin.
