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 1998, this domain has about 28 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. DNS and provider evidence indicate traffic passes through the Fastly CDN, which may support caching and traffic distribution. MX records point to the Microsoft 365 email service. The CNAME points to j.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: CSP, Referrer-Policy, Permissions-Policy. Debug-related headers are present: x-debug-info. 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 response header indicates a CDN or caching proxy in the delivery path. No CORS permission header was found, so browsers normally restrict cross-origin script access.
