The website problem you may not know you have
Your website is live.
But can everyone see it?
You paid to build it. You pay to host it. You pay to bring customers to it. But internet providers, security filters, and network restrictions may prevent some visitors from reaching your website — and you might never know.
Reachability signals vary by network — we help you find out.
Global HTTP Ping & Reachability Check
Powered by the open-source Globalping probe network. Execute live HTTP handshakes from real eyeball & datacenter networks in North America, Europe, Asia, and Oceania.
The gap you can't see
Your website builder says it works. That doesn't mean everyone can reach it.
Your website is online.
Your hosting provider confirms the server is running.
Your website looks fine.
You can open it from your own computer and phone.
But what about everyone else?
Some networks and security systems may restrict access without you realizing it.
Your analytics can't count visitors who never reach your website.
The Blocked.org.uk Model: How Telecom Filters Silence Sites
Inspired by the pioneering work of the Open Rights Group (Blocked.org.uk). Modern telecoms, mobile carriers, and residential ISPs employ automatic content filters that mistakenly classify legitimate businesses and charities.
Interactive Case Studies
Real-World ISP Classification Failures
urban-gardens-community.org
Non-profit / Community Charity
Mistakenly categorized under 'Substance/Weapons' due to gardening tools keyword overlap.
Over 60% of mobile and residential broadband visitors received an ISP error page without the charity's knowledge.
Telecom Provider Status Breakdown
Why your analytics never see this: When an ISP parental or security filter intercepts a DNS or HTTP query, the request is rerouted to the ISP's internal splash screen or refused. The visitor never hits your server or Google Analytics tracker.
The principle
They control the filters.
You deserve the facts.
When a website is incorrectly classified or blocked, the business owner deserves clear information and a practical way to challenge the problem. We're here to help uncover those issues and guide the resolution process.
Blocklist Removal, Investigation & Resolution Assistance
Modeled on industry-standard security remediation frameworks like Sucuri and Google Webmaster Guidelines. When security filters incorrectly blacklist your site, we help prepare verified evidence to dispute and overturn the block.
Root Cause Audit
We investigate whether malicious redirects, outdated third-party scripts, SSL misconfigurations, or cross-site contamination caused the classification.
Remediation Roadmap
Clear technical action items for your web developer or agency: cleaning flagged files, securing DNS records (SPF, DKIM, DMARC), and updating certificates.
Formal Review Filing
We compile formal re-evaluation requests submitted through provider portals (Google Search Console, Norton Dispute, Microsoft Security Intelligence).
Reputation Monitoring
We monitor clearing status across global telemetry nodes to verify that red screen warnings and provider firewall bans have cleared.
Common Authority Blocklists We Inspect & Challenge
Independent dispute preparation. We do not represent any single provider and never guarantee third-party removal timelines.
Consumer Advocacy Notice:
Unlike automated tools that promise instant one-click removal, blocklist authorities (such as Google, Sucuri, and Spamhaus) require verified proof that threats or errors have been rectified. Who's Blocking Me? serves as your technical advocate to isolate the issue, generate reproducible reports, and draft formal correction petitions.
