Why Domain Blacklist Monitoring Matters

In today's digital landscape, regulators worldwide are increasingly blocking domains — especially in industries like iGaming, affiliate marketing, and e-commerce. Blocks happen at the DNS, HTTP, and SSL certificate level, making them invisible unless you actively check from real ISP networks. Our platform delivers real-time block detection across 50+ countries, enabling compliance and uninterrupted service.

Monitor Domain Accessibility Worldwide

Check domain status from multiple countries using real ISP connections — not datacenter proxies. ISP-level blocks are only visible from consumer networks. We test via local connections across Europe, CIS, Asia, Latin America, and North America to give you accurate, real-world results.

Built for Regulated & High-Risk Industries

  • iGaming & Online Betting — Stay compliant with national regulators. Detect blocks before they impact your players.

  • Media & Publishing — Ensure global access to sensitive content. Detect censorship across jurisdictions.

  • Affiliate Networks — Reduce traffic loss, protect ROI, and detect partner domain blocks in real time.

  • Fintech & Crypto — Detect ISP-level filtering early. Maintain accessibility in key financial markets.

Protect Your SEO and User Experience

Blocked domains hurt users and search rankings. Search engines may de-rank sites that are inaccessible in multiple regions. Continuous monitoring protects uptime, preserves organic traffic, and prevents wasted advertising spend on unreachable domains.

Frequently Asked Questions

How do you detect domain blocks?▾

We run scheduled checks from multiple countries using real local ISP connections. Our system analyzes DNS responses, HTTP status codes and content, and SSL/TLS certificates to detect DNS poisoning, HTTP redirects to government block pages, certificate-based blocking, and connection resets.

Do alerts work in real time?▾

Yes. When a block is detected, you receive a Telegram notification within seconds. You can also view the full check history and trends in the dashboard.

What countries do you support?▾

We currently support 50+ countries across Europe (including Russia, Turkey, Italy, Spain, Germany), CIS region (Ukraine, Kazakhstan, Belarus), Asia, Latin America, and North America. Each country has multiple ISP connections for comprehensive coverage.

How is this different from uptime monitoring?▾

Uptime monitoring checks if your server is responding. Domain blacklist monitoring checks if users can actually reach your server — ISP-level blocks, DNS filtering, and SSL inspection can make your site unreachable to users even when the server is perfectly healthy.

Can I monitor domains I don't own?▾

Yes. You can monitor any public domain. This is useful for affiliate marketers who want to track the accessibility of partner/operator domains.

Do you offer an API?▾

Yes. Our REST API lets you add/remove domains, trigger checks, and retrieve results programmatically. API access is included in all plans. Full documentation is available in the dashboard.

How much does it cost?▾

Pricing is prepaid — you top up your wallet and each day of monitoring is billed from your balance. There are no subscriptions, no card on file, no auto-charges. The cost is shown when you add a domain. Every new account gets a free trial balance to test the platform.

What industries benefit most from domain monitoring?▾

iGaming and online betting operators, affiliate marketers, media and publishing companies, fintech and cryptocurrency platforms, and e-commerce businesses with international presence. Any business where domain accessibility directly impacts revenue.
