Scraping one page is easy. Scraping ten million pages a day, every day, without a human babysitting it is an exercise in reliability engineering. The proxy is one component; the system around it matters more.
Separate fetching from parsing
Put a durable queue between the thing that downloads pages and the thing that extracts data. When a parser bug ships, you reprocess from stored HTML instead of re-fetching — saving bandwidth and avoiding extra load on the target.
Budget your proxy spend per job
- Cap retries per URL — infinite retries on a dead page quietly drain gigabytes.
- Track success rate per target and alert when it drops; that's your earliest signal of a layout or anti-bot change.
- Prefer the cheapest IP type that works (see our residential-vs-datacenter guide) and only escalate per-target.
None of this is glamorous. All of it is the difference between a pipeline you trust and one you restart every Monday.
