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 1995, this domain has about 31 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 .org 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 192 days remaining.
HTTP and Browser Security
X-Powered-By exposes backend information: WP Engine. The response lacks these common security headers: CSP, Permissions-Policy. 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 identifies nginx without an exact version.
Technology Stack Analysis
The public page identifies WordPress, jQuery, Google Analytics, Amazon CloudFront, nginx without precise versions, leaving fewer clues for version-specific scanning.
Search and Social Sharing
The meta description has 259 characters and may be shortened in search results. Twitter Card metadata is configured. JSON-LD includes Organization data, helping describe the organization as an entity. The title has 39 characters, within a common display range. The observed directives allow indexing and link following.
