Tasks
High-speed fetches on datacenter proxies
Datacenter pipelines fail when teams skip the canary. Prove the origin accepts the IP class, then raise concurrency.
Canary
One URL, one IP, verbose curl. If you see a block, stop and switch product.
Workers
Put credentials in a secret store. Horizontal scale is more workers, not shared passwords in chat.
Errors
Track 403/429/522 separately. 522 belongs to the HTTP 522 guide.
Instructions
1. Canary
curl through one datacenter endpoint.
2. Parser freeze
Save a body sample.
3. Raise concurrency slowly
Watch error rates, not just requests per second.
