Inquiry categories we handle
We actively investigate correspondence related to:
- Speed Test Anomalies: Unexpected script errors, browser console warnings, or measurement stalls during tests on our home page or dedicated tools like the bufferbloat test or packet loss test.
- Factual Corrections to Guides: Changes to vendor streaming bitrates (e.g., Netflix, YouTube 4K), conferencing requirements (Zoom, Microsoft Teams), or broadband policy regulations.
- Browser Compatibility Feedback: Display or execution quirks encountered on specific operating systems, mobile browsers, or assistive technology screen readers.
- Contractual & Syndication Inquiries: Formal agreements for educational content syndication, corporate diagnostic integration, or commercial partnerships.
Submitting technical engine bug reports
If our speed test fails to complete, produces an error alert, or behaves unexpectedly in your browser, including the diagnostic parameters below enables our engineers to reproduce and resolve the issue quickly:
| Required Parameter | Example & Diagnostic Purpose |
|---|---|
| Browser Name & Exact Version | Chrome 134, Firefox 136, Safari 18.2, or Edge 134. (Different browser rendering engines implement WebRTC and Resource Timing APIs with varying constraints.) |
| Operating System & Device Type | Windows 11 desktop, macOS Sequoia, iOS 18 iPhone, Android 15, or Linux Ubuntu 24.04. |
| Local Connection Interface | Direct Cat 6 Ethernet cable, 5 GHz Wi-Fi 6, 2.4 GHz Wi-Fi, or cellular 5G mobile data. |
| Stalled Test Phase & Error Text | Identify whether the failure occurred during Ping, Download, Upload, or WebRTC Packet Loss, and include the exact error message displayed. |
| Network Intermediaries & Extensions | Note whether an active commercial VPN, corporate proxy, DNS-over-HTTPS resolver, or ad-blocking browser extension was enabled. |
For more details on how our engine executes each phase, consult our Methodology specification.
Submitting evidence-backed corrections
We are dedicated to maintaining absolute technical accuracy across our educational content. If you identify an outdated figure, inaccurate network calculation, or incorrect vendor requirement in any of our guides:
- Cite the exact URL of the page containing the disputed text.
- Highlight the specific sentence, metric, or table cell you believe needs updating.
- Provide a direct link to authoritative primary documentation (such as an IETF RFC standard, official FCC broadband release, or direct vendor support documentation from Netflix, Zoom, or Microsoft).
All correction requests are evaluated against our published Editorial Policy. When a material update is confirmed, the page text and verification timestamp are updated promptly.

Privacy inquiries & data handling
As detailed in our Privacy Policy, InternetSpeedTest.online does not maintain user accounts, does not store visitor profiles, and does not record test measurements in a server database. Recent test history is stored exclusively in your own browser's local storage and can be erased instantly via the "Clear history" button.
If you email us, your email address and message contents are retained strictly to investigate and reply to your inquiry. To submit a privacy question or request deletion of correspondence, email our administrator at [email protected].
Issues outside our operational scope
To prevent delay and confusion, please note that InternetSpeedTest.online is an independent measurement utility, not an internet service provider. We have no access to your telecom provider's backend systems and cannot assist with:
- ISP Billing & Subscription Plans: We cannot access your broadband contract, alter data plans, or troubleshoot account billing disputes.
- Physical Line Faults & Area Outages: We cannot repair severed fiber lines, damaged street drop cables, or neighborhood node failures. Contact your ISP's technical support department directly.
- Customer Gateway & Router Hardware: We cannot remotely configure home router passwords, adjust firewall firmware on ISP-rented hardware, or dispatch field technicians.
- Regulatory Legal Claims: While our diagnostic tools provide evidence useful when discussing service quality, formal contractual disputes must be filed directly with your national regulator (e.g., the FCC in the United States, Ofcom in the UK, or CRTC in Canada). Review our Disclaimer for details.
