Why your web scraping keeps getting blocked
Your scraper works for the first thousand requests, then suddenly every request returns 403 or CAPTCHA. The site didn't change its API — your IP got flagged.
What's causing it
Datacenter IP detection
Most websites maintain blocklists of known datacenter IP ranges (AWS, GCP, DigitalOcean). Requests from these IPs are blocked or heavily rate-limited before any content is served.
No IP rotation
Sending thousands of requests from a single IP triggers rate limits regardless of proxy type. Without rotation, even residential IPs get temporarily blocked.
Predictable request patterns
Scrapers that hit pages in sequential order at consistent intervals are easy to fingerprint. Combined with a flagged IP, this guarantees a block.
The fix
Rotating residential proxies
Each request gets a new residential IP from a different household. Sites see organic traffic patterns instead of a bot farm.
Smart proxy rotation
Automatic rotation with session stickiness when needed — new IP per request for scraping, sticky IP for login flows.
Datacenter proxies for low-risk targets
For sites without aggressive anti-bot, fast datacenter proxies at 10x lower cost handle high-volume extraction efficiently.

Common questions
Residential vs datacenter for scraping?
Use datacenter for sites without anti-bot (internal tools, APIs, open data). Use residential when you hit CAPTCHAs or 403 blocks on datacenter IPs.
How many requests per IP?
It varies by site. Start with 1 request per IP (full rotation) and increase only if the target site allows it. Monitor 403 rates to find the threshold.
Do I need an anti-detect browser for scraping?
Only for JavaScript-heavy sites that fingerprint browsers. For API and HTML scraping, proxies alone are sufficient.
