speedtest.net Overview

Description of speedtest.net

speedtest.net appears to be the official website for Speedtest by Ookla, a widely used internet performance testing service. The site lets visitors measure download speed, upload speed, latency, and related connection metrics from their browser or apps, and the homepage screenshot matches that purpose with a prominent test interface and server selection options.

Based on the page title, metadata, and linked domains, the service appears to be operated within the Ookla/Ziff Davis ecosystem. Its categories are consistently associated with information technology and software, and its long operating history and strong traffic rank suggest it is an established technology platform rather than a newly created or single-purpose site.

Safety Assessment for speedtest.net

The available scan data is broadly reassuring. At the time of this scan, 0 out of 91 security engines flagged the domain, and the checked threat databases did not report listings associated with phishing or malware distribution. The domain is also long-established, with a creation date in 1999, which generally reduces the likelihood of opportunistic abuse compared with newly registered domains.

One malware scan did mark a single JavaScript asset as malicious, but this appears to be an isolated finding without corroboration from the broader engine consensus or blacklist checks. In cases like this, a lone heuristic or file-level alert may reflect a false positive, obfuscated production code, or a scanner sensitivity issue rather than confirmed harmful behavior. No external links or referenced domains were flagged in the scan results.

Based on available data, no significant threats were detected at the time of this scan.

Technical Description

The site uses a valid SSL/TLS certificate issued by GlobalSign, with the certificate shown as valid until 2026-11-08. It is hosted on Fastly infrastructure and uses AWS nameservers, which is consistent with a large-scale content delivery and cloud-based deployment model. The domain has a very long registration history and is currently registered through a corporate registrar.

DNSSEC appears to be unsigned, which is not uncommon but means DNS responses do not benefit from DNSSEC validation. No DNS-based mail-reputation blocklist hits were reported in this scan, and no major infrastructure-level security concerns were evident from the provided data.
