## Briefing
- Crawlbase: Crawlbase published a technical blog post describing a smart AI proxy rotation method in Python that uses exponentially weighted moving averages for success and latency, plus a circuit breaker, instead of simple round-robin.

## Why it matters
This post highlights a shift from naive round-robin proxy rotation to adaptive, health-aware strategies that can significantly improve reliability and success rates in web scraping at scale. For practitioners, understanding EWMA-based scoring and circuit breakers is key to building robust extraction pipelines that handle proxy failures gracefully.

## Watch next
Will other proxy vendors adopt similar health-scored rotation algorithms as a standard feature in their SDKs?
