Where is eharmony.com hosted?

The first address resolves to infrastructure in Toronto, Canada.

The network is operated by Cloudflare, Inc. (AS13335 Cloudflare, Inc.).

Hosting location describes where the responding server sits, not where the business is. A CDN will report its nearest edge rather than the origin.

What is eharmony.com running on?

eharmony.com exposes 2 identifiable technologies: WordPress, Cloudflare.

WordPress is identifiable from its asset paths, so the platform is public knowledge regardless of whether the version is hidden. That matters mainly for patching discipline: known-platform sites are scanned automatically and constantly.

Cloudflare sits in front of the origin, so the server header, IP addresses and response timing describe the edge rather than the machine actually running the site.

• WordPress
• Cloudflare

Does eharmony.com set the usual HTTP security headers?

It sets 4 of 6. The ones not present are: X-Frame-Options, Permissions-Policy.

Does eharmony.com allow AI crawlers?

robots.txt names no AI crawler specifically, so they fall under the wildcard rule, which does not disallow them.

What is eharmony.com built with?

The homepage exposes these fingerprints: WordPress, Cloudflare. A site behind a CDN or rendered server-side may use more than it reveals.

Where does this data come from?

Every figure was measured by our own server on 5 October 2026: DNS lookups, one HTTPS request to the homepage, a TLS handshake and a request for robots.txt. No third-party SEO API is involved.

Is any of this traffic or authority data?

No. Traffic, authority and ranking figures cannot be measured by inspecting a domain, only modelled. Everything here is a direct observation.

I own eharmony.com and want this page removed.

Ask through the contact page on this site, from an address at the domain, and the report will be taken down. It only ever shows what the domain already serves publicly.
