Abuse Mitigation via IP-based Rate Limiting

Problem

Abusive traffic patterns (including attack-like bursts) threatened availability and could degrade auction integrity.

Solution

Added IP-based request limiting policies and tuned thresholds to protect critical endpoints while preserving normal user flows; monitored and adjusted rules based on observed traffic.

Impact

• Reduced attack blast radius and improved service stability during abnormal traffic spikes.
• Helped maintain auction availability during peak events by preventing overload from abusive clients.

Highlights

• Implemented IP-based request limiting policies to reduce blast radius during abnormal traffic spikes.
• Focused protection on critical auction endpoints to preserve bidding stability.
