A web crawler successfully crawled over 1 billion pages in 25.5 hours for approximately $462, utilizing a cluster of 12 optimized nodes. The design focused on high concurrency, fault tolerance, and adherence to web crawling etiquette, while primarily fetching HTML content and avoiding modern JavaScript-heavy pages. The project aimed to explore the feasibility of large-scale web crawling given advancements in technology since earlier benchmarks.
