Website Overview

An established domain and managed infrastructure suggest continuity of operations and may support dependable delivery, although neither guarantees service quality. Page metadata, canonical configuration and social previews work together to provide more consistent search and sharing presentation.

Domain and Registration

Registered in 2006, this domain has about 19 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 registrar is Tucows Domains Inc., a widely used domain service provider. 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 Amazon Route 53, indicating managed DNS hosting. MX records point to the Mailgun email service. No CNAME was found; the observed records resolve directly to addresses. SPF and DMARC are configured. DKIM status is unknown.

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 within the Amazon cloud or CDN ecosystem. The certificate is valid for about 394 days in total, with 149 days remaining.

HTTP and Browser Security

The response lacks these common security headers: CSP, Permissions-Policy. No X-Powered-By header was found, reducing one common source of backend fingerprinting information. The x-cache, via response header indicates a CDN or caching proxy in the delivery path. No obvious internal addresses or debug information were found in the headers. The Server header contains the custom value AmazonS3.

Technology Stack Analysis

The public page identifies Amazon CloudFront without precise versions, leaving fewer clues for version-specific scanning.

Search and Social Sharing

Twitter Card metadata is configured. The title has 10 characters, within a common display range. A meta description is present, with 88 characters. The observed directives allow indexing and link following. No Generator meta tag is publicly exposed.
