Subsets of customers in major metro regions such as Chicago and Miami have been experiencing short disruptions in connectivity for the past few weeks. Specialized DDoS protection providers and infrastructure networks worldwide are currently facing an extraordinary threat: a massive botnet campaign known as Aisuru, the same botnet responsible for the record-breaking 22 Tbps attack against Cloudflare. This botnet is launching attacks that exceed multiple terabits per second in volume, and subsequently creating congestion not only at targeted endpoints, but throughout the broader Internet infrastructure, affecting transit providers and peering points that serve traffic beyond any single network.
It's important to recognize that attacks of this magnitude affect the entire Internet ecosystem. Protection providers including OVH, GSL, CosmicGuard, NeoProtect, and others have all seen similar challenges. When attackers direct multi-terabit floods toward a mitigation provider's infrastructure, temporary disruptions can occur even with the right mitigation in place. No provider can guarantee complete immunity against attacks of this unprecedented scale.
Services with strict latency and packet loss requirements—such as real-time gaming, VoIP, and live streaming—are especially vulnerable during these events. Even when our upstream mitigation provider reroutes traffic in response to attacks, the initial attack wave may have already caused timeouts, lag, or connection drops before mitigation takes effect.
We want to assure you that maintaining service stability is our highest priority. Our team is monitoring the situation 24/7, working directly with our mitigation partner to minimize exposure and respond to evolving threats. This represents an industry-wide challenge affecting networks globally, but we remain fully committed to protecting your services and maintaining the best possible stability under these extraordinary circumstances.
