Solana withstands massive DDoS pressure

Heavy DDoS traffic reportedly hit the network, yet Solana maintained uptime and fast confirmations, strengthening the view that its recent reliability upgrades are paying off.
Evidence of full uptime during an alleged DDoS campaign is reshaping views on Solana’s ability to handle internet scale stress.

Reports suggest Solana was targeted by a sustained DDoS campaign in mid-December, with peak traffic estimates close to 6 Tbps. Public dashboards showed full uptime and no visible disruption for users.

Recent upgrades appear central to the outcome, as they move spam filtering and prioritisation closer to the network edge. QUIC traffic handling, stake-weighted routing and local fee markets helped limit congestion.

Focus is shifting from outage risks to resilience under pressure. The episode suggests major blockchains are now engineered and attacked like Tier 1 internet infrastructure.
