Website Overview

An established domain and managed infrastructure suggest continuity of operations and may support dependable delivery, although neither guarantees service quality.

Domain and Registration

Registered in 2004, this domain has about 22 years of history. That suggests continuity, although ownership and purpose may have changed. Transfer-protection status is present, helping reduce the risk of unauthorized domain transfers. The domain uses the common .com extension, which is not an independent safety signal.

DNS and Email

The lowest TTL is 60 seconds, supporting rapid record changes at the cost of more frequent lookups. Nameservers are provided by worldnic.com, indicating managed DNS hosting. DNS and provider evidence indicate traffic passes through the Fastly CDN, which may support caching and traffic distribution. MX records point to the arsmtp.com email service. The CNAME points to n.sni.global.fastly.net, associated with Fastly.

TLS and Certificates

The certificate uses an RSA 2048-bit public key, offering broad client compatibility. The server supplied a complete certificate chain. No organization name is present in the certificate; the available fields are consistent with domain validation. The certificate was issued by Let's Encrypt, commonly associated with automated certificate services. The certificate's total validity is about 89 days, consistent with a short renewal cycle.

HTTP and Browser Security

The response lacks these common security headers: Referrer-Policy, Permissions-Policy. Debug-related headers are present: x-debug-url. Check whether they are needed in production. No X-Powered-By header was found, reducing one common source of backend fingerprinting information. The x-cache, x-served-by, via response header indicates a CDN or caching proxy in the delivery path. The Server header identifies nginx without an exact version.

Technology Stack Analysis

The public page identifies jQuery, Fastly, nginx without precise versions, leaving fewer clues for version-specific scanning.

Search and Social Sharing

No Open Graph metadata was detected, so social previews may depend on platform inference. JSON-LD includes Organization data, helping describe the organization as an entity. The title has 22 characters, within a common display range. A meta description is present, with 48 characters. The observed directives allow indexing and link following.
