What is cnlab and why do Swiss people search for it?

Cnlab AG is a Swiss network engineering company that operates the official speed test tool for BAKOM (Switzerland's Federal Office of Communications). When Swiss ISPs advertise speeds, BAKOM uses cnlab's measurements to verify compliance. Consumers search for 'cnlab speed test' to access this government-backed tool.

Why do cnlab and other speed tests show different results?

Cnlab's test servers are hosted within Swiss peering points, giving very low latency. Other speed tests may route through international servers. The measurement methodology also differs — cnlab uses multiple parallel connections. Both are valid; cnlab's results are best for comparing against your ISP's advertised speed.

Cnlab Speed Test — Switzerland's Official Measurement

If you are Swiss and searched for "speed test," you have likely encountered cnlab. Cnlab AG is a Zurich-based network engineering company that operates the official speed measurement tool for BAKOM — Switzerland's Bundesamt für Kommunikation (Federal Office of Communications). When Swiss regulators verify that internet providers deliver the speeds they advertise, they use cnlab's platform.

This page provides an alternative speed test you can use alongside cnlab to cross-check your results. Using multiple speed test tools gives you a more accurate picture of your actual connection performance.

Why Cnlab Matters in Switzerland

Swiss internet is among the fastest and most expensive in the world. When you pay CHF 60-120/month for a Swisscom fibre connection, you deserve to get what you are paying for. BAKOM mandates that ISPs disclose their speeds honestly, and cnlab provides the measurement infrastructure to enforce this.

The cnlab speed test (cnlab.ch/speedtest or test.cnlab.ch) is particularly valued because:

Servers are in Switzerland: Hosted at major Swiss peering exchanges (SwissIX), minimising international routing overhead.
Multi-threaded testing: Uses multiple parallel TCP connections to saturate your link properly.
ISP-neutral: Not operated by any ISP, removing conflict of interest.
Regulatory weight: Results from cnlab carry weight in complaints to BAKOM about underperformance.

Comparing Speed Test Results

Factor	Cnlab	SpeedMbps (This Tool)
Server Location	Swiss peering points	Cloudflare global CDN (Swiss PoPs)
Test Method	Multi-threaded TCP	Multi-threaded via Service Workers
Best For	Verifying ISP-advertised speeds	Real-world internet performance
Data Privacy	Swiss data protection law	No account required, minimal data

If cnlab shows 950 Mbps and this tool shows 880 Mbps on a 1 Gbps plan, both are correct — the difference comes from server proximity and routing. Your ISP is delivering the promised speed.

Cnlab Speed Test FAQs

What is cnlab and why is it important in Switzerland? Cnlab AG is a Zurich-based network engineering company that runs the official speed test for BAKOM (Switzerland's Federal Office of Communications). When regulators verify ISP-advertised speeds, they use cnlab's platform. Results carry regulatory weight for speed complaints.

Why do cnlab and other speed tests show different numbers? Cnlab servers are hosted at Swiss peering points (SwissIX), giving very low latency. Other tests may route through international servers. Both are valid — cnlab is best for verifying your ISP's advertised speed; independent tests show real-world internet performance.

How do I file a speed complaint with BAKOM? Document multiple tests across different times of day using a wired connection. Use both cnlab and an independent speed test. Screenshot the results. Submit your complaint via bakom.admin.ch with your ISP contract details and test evidence.

Is cnlab independent from ISPs? Yes. Cnlab is not operated by any ISP, removing conflict of interest. This ISP-neutral position is why BAKOM chose them as the official measurement platform.

Should I test on cnlab or here? Use both. Cnlab measures your line speed to Swiss servers (closest to ISP-advertised conditions). This tool measures real-world performance through Cloudflare's CDN. If cnlab shows full speed but our tool shows less, your ISP peers well domestically but may have international routing issues.

Swiss ISP Speed Check

Swisscom — Switzerland's premium fibre provider. FTTH up to 10 Gbps. Consistently ranks highest in cnlab measurements.
Quickline — Regional cable alliance. Good speeds via DOCSIS 3.1 but asymmetric upload.
Teleboy — Budget-friendly Swisscom fibre reseller with bundled IPTV.
Sunrise — Major competitor with own infrastructure. Good urban coverage.
Salt — Mobile-first with aggressive fixed broadband pricing.

Filing a speed complaint: If your speed consistently measures below what your ISP advertises, document multiple tests (different times of day, wired connection) using both cnlab and an independent tool. Submit your complaint to BAKOM via bakom.admin.ch.
