NetBlocks defends your right to privacy, and we work to protect your digital rights whenever you visit our websites and engage with us online or offline.

Data Usage Policy

Metrics We Collect

We strive to collect as little data as we need to further our mission.

We collect information regarding visits to this website and sites that are linked to or referenced from this website. We log IP addresses, browser, operating system, visiting time (local and server), pageviews, load times, request headers including referring site information, and reachability data for both NetBlocks and external online properties. Performance data and error logs are sampled for the purpose of diagnosing network disruptions and outages and improving service quality.

Your Consent

We will not associate data gathered from this site with sensitive personal data such as your name or account details from any source unless you explicitly submit that information, or unless you otherwise provide consent and explicitly opt-in for services and facilities that involve the processing of said sensitive personal data.

Our Data Pledge

We will never use analytics or measurement tools to track, collect or correlate sensitive personal data such as names or accounts pertaining to visitors of our site without consent.

Neither we nor our partners will seek to link performance metrics with the identity of an individual, other than to mitigate attacks on technical infrastructure or vital interests as permitted and/or required by law.

Network Quality Monitoring

This site performs performance checks of resources hosted on external websites in order to assess and report on the network quality available to visitors. The set of monitored external websites seeks to cover mainstream platforms that are frequently accessed by the public, and the set varies based on coarse-grained information about the visitor’s country and the time of day. The monitoring system respects client-side policies configured by the visitor to restrict cross-origin resource loading whether by means of a browser setting or via third-party blocking extensions.

The performance and reachability of external websites is monitored by loading basic resources such as an icon or image, or by performing an HTTP HEAD request. The browser is instructed to suppress third-party cookies, credentials, trackers and referrer information where possible to preserve privacy. Aggregated, anonymized network quality statistics are used to inform reporting on network outage incidents in the public interest.

NetBlocks and its authors are not responsible for the privacy practices or the content of monitored platforms. No endorsement of online content linked to, reported on or tested by NetBlocks calculators and measurement tools is expressed or implied. Suggestions for the addition or removal of platforms from the set of monitored sites can be made via our contact page.

Social Media Policy

We use social media, social networking, telephony and mailing services to advance our mission. Some of these platforms and applications are provided by third party service providers. Please see their privacy policies for more information and contact us if you have specific concerns or recommendations, including but not limited to Twitter and Facebook.
