Understanding the Recent DDoS Attack Against Read the Docs
TL;DR
Read the Docs faced a record DDoS attack in June 2026, peaking at 5.5 million requests per minute, which tested their defenses and incident response. Despite existing rate limiting, the attack's sophistication highlighted the need for improved strategies to maintain service availability.
✦ Why It Matters
Evaluate and enhance your DDoS mitigation strategies to better handle sophisticated attacks.
Key Takeaways
- Implement aggressive caching for all endpoints to reduce attack surfaces.
- Use targeted rate limiting to differentiate between legitimate and malicious traffic.
- Regularly review and update defense rules using Infrastructure as Code.
- Monitor traffic patterns to identify and respond to adaptive attack strategies.
How It Works
Read the Docs utilized a combination of edge caching and targeted rate limiting to manage the DDoS attack. By caching responses aggressively, they minimized the load on their origin servers.
Targeted rate limiting was employed to challenge suspicious traffic while allowing legitimate users to access the site without friction.
