Please note that a speedtest is an indicator, various factors can affect performance. To get a most accurate speedtest as possible, use a Ethernet connection (Gig-E with proper Cat-5E or Cat-6 cabling), not WiFi (which can have interference and a lot of other factors). Also ensure that that is the only device using the link in question. Ensure that your firewall is disabled (eg. the Windows Firewall causes performance issues). Ensure that you are using recent hardware that can actually perform at high speeds.

Resolver Restrictions

Note that due to Swiss law, we are blocking certain domains/hostnames. The blocked domains are sourced from:

Additionally we are blocking, voluntarily, malvertised domains to protect our customers from Internet badness.

Not using our DNS recursor bypasses these blocks, customers can freely reconfigure their devices. Technically we are using RPZ.

The host gets redirected to when being blocked for the Geldspielgesetz (BGS) does not log either. We suggest using HTTPS, as we do not have the proper SSL certificate for other hosts and your browser will then warn about the SSL certificate.

Our systems do not log or otherwise store queries due to FADP (Federal Act on Data Protection), DSGVO (Datenschutz-Grundverordnung) and GDPR (General Data Protection Regulation), which Quickline adheres to as we have EU-national customers residing in EU-countries, while sometimes using Quickline from Hotels, Vacation rentals or their part-time residences in Switzerland.

Technical Details

We use a combination of PowerDNS dnsdist and noqosho, with backup service provided by PowerDNS Recursor (pdns) and NLNetLabs unbound to allow for software resiliency in case our primary solution has issues.

We host a AS112 (RFC7534) node on our authoritive platform, used by our recursive servers. (dig txt +short +norec reveals when that is used.
