What Is a Rate Limiting / Possible DDoS?
A 429 status code means the server is rejecting requests because too many are being sent in a short period.
This could be caused by legitimate traffic spikes or automated bots overwhelming your server.
If the requests come from a limited set of IPs, it may indicate a bot attack.
How to Defend Against This Threat
Implement rate limiting at the server or CDN level.
Use services like Cloudflare to filter bot traffic.
Block suspicious IP addresses.
Enable caching to reduce server load.
Monitor traffic patterns for anomalies.
