Website Overview
An established domain and managed infrastructure suggest continuity of operations and may support dependable delivery, although neither guarantees service quality. Several search or sharing settings need attention. Together they may make snippets, preview images or preferred URLs less consistent across platforms.
Domain and Registration
Registered in 1996, this domain has about 30 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 Amazon Route 53, indicating managed DNS hosting. MX records point to the Google Workspace 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 197 days in total, with 55 days remaining.
HTTP and Browser Security
The response lacks these common security headers: HSTS, Referrer-Policy, Permissions-Policy. No X-Powered-By header was found, reducing one common source of backend fingerprinting information. CORS permits the specified origin https://www.infoq.com. No obvious internal addresses or debug information were found in the headers. The Server header identifies Apache without an exact version.
Technology Stack Analysis
The public page identifies Google Tag Manager, Google Analytics, Apache without precise versions, leaving fewer clues for version-specific scanning.
Search and Social Sharing
The title has 68 characters and may be truncated in search results. Open Graph is partially configured; og:title, og:description, og:type is missing. The page declares 5 language or regional alternatives using hreflang. A meta description is present, with 133 characters. The observed directives allow indexing and link following.
