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 2007, 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 observed email authentication setup is incomplete: DMARC is missing. Nameservers are provided by netfirms.com, indicating managed DNS hosting. MX records point to the astronomyniagara.com email service. No CNAME was found; the observed records resolve directly to addresses. DNSSEC signatures were not detected, so this additional DNS authenticity protection is not confirmed.
TLS and Certificates
The certificate issuer is DigiCert Inc, a commercial certificate authority. 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 is valid for about 198 days in total, with 136 days remaining.
HTTP and Browser Security
X-Powered-By exposes backend information: PHP/7.4.33. The response lacks these common security headers: HSTS, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, clickjacking protection. No obvious internal addresses or debug information were found in the headers. Cookie security attributes are unknown. No explicit CDN or WAF marker was found in the response headers.
Technology Stack Analysis
The public page identifies PHP without precise versions, leaving fewer clues for version-specific scanning.
Search and Social Sharing
No homepage meta description was detected, leaving snippet selection more dependent on page text. No homepage canonical URL was detected. If duplicate URLs exist, consolidation may be less explicit. No Open Graph metadata was detected, so social previews may depend on platform inference. The title has 59 characters, within a common display range. The observed directives allow indexing and link following.
