Datacenter is the first route to test
Datacenter proxies are the first route I test on plain public work unless there is already evidence the target rejects hosting ASNs. They are cheaper than residential, usually faster, and not automatically worse. They are just easier for some sites to identify.
Run one route first. If the result is bad, scaling only hides which part failed and makes the provider meter harder to explain.
Volume Residential costs $0.89/GB, billed per transferred byte. Datacenter is cheaper. At 50 GB the savings are real only if the accepted rows stay close. A small pilot answers that faster than a debate.
This is a cleaned-up sample from a public-records-style target, with the host removed.
route: datacenter
sample: 1,200 requests
2xx: 1,087
3xx: 41
4xx from target: 38
connect errors: 14
timeouts: 20
provider-metered bytes: 2.06 GB
usable rows: 1,061That sample does not show an IP-class problem. I would keep testing on datacenter before moving to residential. Before trusting it, rerun at a busier hour and check a larger slice.
Targets that pass on datacenter
Public catalogs, documentation sites, RSS-style feeds, open research endpoints, and authorized APIs often work fine on a hosting ASN. The target does not treat that fact alone as a reason to fail the request. Request shape still matters. Dirty ranges and noisy neighbors still matter. The proxy type is not the only variable.
When to move to residential
Move to residential when the same request behaves differently across the two pools. If the datacenter run accumulates 403s or challenges while the residential run clears with the same headers, timing, and auth, that is useful evidence. If both runs fail, the problem is somewhere else.
The somewhere else is usually boring: bad headers, expired tokens, wrong parameters, a parser waiting for the wrong field, or a retry rule hiding the original failure. Those bugs get blamed on proxies because the final error surfaces near the network layer.
Provider-metered bytes vs app-level counters
App dashboards undercount what happened on the wire. They show saved rows, completed responses, or parsed payload size. The proxy meter sees retries, redirects, block pages, TLS overhead, and failed attempts. A datacenter route that looks clean in the app can still be wasteful if the proxy export tells a different story.
The Proxynade dashboard network logs show host, outcome, latency, and byte totals per request. Usage logs export as CSV. Compare those numbers against your app-level counters before concluding a route is efficient.
The decision rule
Datacenter proxies are good enough when they return the permitted data, keep failure rates stable, and beat residential on cost per successful result. If that stops being true, test Volume Residential at $0.89/GB. Premium Residential at $5.00/GB is a later test, not the first excuse to skip measurement.
