🔒DDoS Attack Peaks at 500-600 Gbit/s, Overloads Infrastructure
Infrastructure Overwhelmed by DDoS, Impacting Customer Access
TL;DR
A DDoS attack on August 11, 2026, peaked at 500-600 Gbit/s, overwhelming infrastructure and affecting customer access. The attack used UDP amplification, targeting various services and highlighting the need for advanced DDoS protection.
A DDoS attack on August 11, 2026, peaked at 500-600 Gbit/s, overwhelming our infrastructure and affecting customer access to services like Deploio, Cockpit, and the ticketing system. The attack used UDP amplification, targeting new IP addresses and overloading individual services regardless of bandwidth. This incident highlights the need for advanced DDoS protection, as blackholing and filtering inside the network were ineffective once the uplink was full. The attack ended with the migration of exposed applications behind a European CDN with built-in DDoS protection, underscoring the importance of robust security measures for cloud services.
Key Points
An attack on August 11, 2026, targeted a customer's connection, peaking at 500-600 Gbit/s, exceeding uplink capacity.
Two upstream providers confirmed 260 Gbit/s of the attack, using UDP amplification and spoofing the victim's address.
The attack overloaded individual services regardless of bandwidth, affecting services like Deploio, Cockpit, and the ticketing system.
Blackholing and filtering inside the network were ineffective once the uplink was full, highlighting the need for advanced DDoS protection.
The attack ended with the migration of exposed applications behind a European CDN with built-in DDoS protection, starting on August 11.
Why It Matters
If you manage cloud services or rely on internet connectivity, this DDoS attack highlights the critical need for advanced DDoS protection. The attack overloaded infrastructure despite filtering and blackholing, underscoring the importance of robust security measures for cloud services. The incident also revealed gaps in automated attack detection and blackholing configurations, which are now being addressed.
