How do I check if my redirect chain is broken in a specific country?
Published 2026-05-27 · 8 min read
TL;DR
Trace the full chain (tracking link → tracker → prelander → offer page) from real residential and mobile ASNs inside the failing country. Capture every hop's URL, status code, response time, and the final screenshot. Compare against the same trace from a clean country and from a datacenter probe. The first hop whose URL differs, whose status is non-200/non-302, or where the chain stops short, is the broken hop. Fix that specific hop — not the campaign URL as a whole.
A redirect chain is a series of independent failures
Every hop in a paid-traffic redirect chain is a separate domain that can be filtered, rate-limited,
or hijacked independently of the others. A typical chain has 2–5 hops:
ad-network → tracker → (optional prelander) → offer-page. The chain only works end-to-end
if every domain along the way is reachable from the user's network. Block any one — even just the
middle one — and the user lands on a partial page, an error, or the wrong final URL, even though the
offer page itself is perfectly up.
This is why the "is my site up?" question is misleading for affiliate traffic. The site is up. The chain is broken — in one country, on one carrier, at one hop. Standard uptime monitors never see this because they only check the final URL from a datacenter probe.
How to find the broken hop (step by step)
- 1
Document the expected chain end-to-end. List every hop with the expected status code (typically
302for redirects,200for terminal) and the expected next URL. - 2
Trace the chain from real consumer ASNs in the failing country. Follow every redirect manually — capture URL, status, response time, and final screenshot. Do not collapse the chain; the per-hop detail is the diagnostic.
- 3
Trace the same chain from a clean country and from a datacenter probe. The clean references tell you what "working" looks like. Anything that differs in the failing country is a candidate.
- 4
Compare hop by hop. First mismatched URL, first non-200/non-302 status, or first hop where the chain stops short → that hop is the failing one. Inspect headers and screenshot for the actual cause (CF challenge, ISP block page, DNS hijack, origin error).
- 5
Match the cause to a fix. Tracker blocked → swap tracking domain. Prelander host blocked → move prelander. Origin blocked → rotate to mirror. DNS hijack → escalate carrier abuse, switch domain.
- 6
Set per-hop, per-ASN continuous alerts. Alert on any hop that returns a non-expected status, a URL outside expected pattern, or a final screenshot diff. Pause campaigns into the affected country until the chain clears.
Common per-hop failure patterns
| Hop type | Typical failure | Signature | Fix |
|---|---|---|---|
| Ad-network click URL | CF / WAF challenge for residential traffic | cf-ray + interstitial | Escalate via ad-network rep / change publisher |
| Tracker (Voluum / RedTrack / Binom) | Tracking domain on regulator blocklist | 451 / DNS error from carrier ASNs | Rotate tracking domain (new CNAME / subdomain) |
| Prelander host | Hosting IP on WAF deny list | 403 on residential / mobile only | Move prelander to clean host / CDN |
| Offer page | Country block on the brand domain | 451 / block page across all carriers | Rotate to mirror for that country |
| Any hop | Carrier DNS hijack | Final URL ≠ expected; lands on gov / ISP page | Escalate carrier abuse; change domain |
Why this matters
Most teams react to a country-specific drop by checking the offer page and finding it up — then concluding the issue is traffic quality. The actual issue is usually one of the upstream hops, and the fix is much smaller than they think: a tracking-domain rotation, a prelander move, or a different CDN account. The lost diagnostic time is the cost. A per-hop, per-ASN trace turns "the campaign is broken in Brazil" into "the prelander host is on a Vivo deny list — swap it" within minutes.

FAQ
How do I check if my redirect chain is broken in a specific country?
Trace the full chain (tracking link → prelander → offer page) from real residential and mobile ASNs in the target country. Capture every hop's URL, status code, response time, and (for the final hop) screenshot. Compare against the same trace from a clean country. Any hop where the URL differs, the status code is non-200/non-302, the chain stops short, or a hop redirects to a block page is the failing hop. The fix targets that specific hop, not the campaign URL as a whole.
Why does my redirect chain work in some countries but not others?
Each hop in the chain is a separate domain that can be filtered independently. The tracking domain might be on a regulator blocklist in one country; the prelander host might be on Cloudflare with rules that drop residential mobile IPs; the offer page might be fine. The chain only works end-to-end if every hop is reachable from the user's network. Block any one of them and the user lands on an error page even though the offer page itself is up.
How many hops does a typical paid-traffic redirect chain have?
Most affiliate / media-buying chains have 2 to 5 hops. A common pattern is: ad network click URL → tracker (Voluum / RedTrack / Binom) → optional prelander → offer page. Each step is a separate domain — and each can be blocked, rate-limited, or hijacked separately. The more hops, the more surface area for a country-specific break.
Which hop fails most often?
The tracking domain is the most common failure point because it's reused across many campaigns — a single blocklist hit on the tracker kills traffic for every campaign using it. The prelander host is the second most common because it's often on cheap shared hosting that ends up on WAF deny lists. The final offer page usually fails last because operators maintain mirror inventory for it specifically.
What does it mean if the chain ends on a different domain than expected?
Either a regulator-level DNS hijack (the user's ISP rewrote the destination to a government landing page) or a compromised redirect (a tracker / prelander host was hacked and redirects somewhere else). Both are critical: the first means you're blocked in that country; the second means your campaign infrastructure has been compromised and traffic from all countries may be affected.
How do I monitor the full chain continuously?
Run per-ASN traces against the entry URL (the tracking link) — not just the final offer page. Each hop's URL, status, response time, and the final rendered screenshot are the four signals you need. Set alerts on: any non-2xx / non-3xx status at any hop, a final URL that doesn't match the expected pattern, a chain that terminates short, or a hop where response time spikes (often the signal that a hop is being challenged but eventually succeeds).
