Download websites that use EdgeCast

A CDN leaves its signature in the plumbing rather than in the page, which is the only reason EdgeCast shows up in a technology scan at all. Nothing about the design of a site tells you who moves its bytes. The evidence sits in response headers, in the hostnames attached to image and script URLs, and in cache identifiers that most visitors never see, and any of those can be renamed by a customer who prefers not to advertise the arrangement.

The brand has outlived the company that created it. Our vendor of record is Edgio, while the product name and the original domain both predate that owner, and a gap of that kind is what an acquisition leaves behind in a technology index. Anyone matching this data against a supplier list or a competitor's public account roster needs to hold both names, because contracts follow the vendor and fingerprints follow the product.

As of November 2026 the EdgeCast fingerprint matches 12 sites, a platform first sold in 2006 under a Proprietary licence. A count that size is worth reading as residue rather than as market position. Sites change delivery network without touching a line of their own code, so a footprint in this category can drain away over a couple of quarters while everything visible on the page stays identical. The reverse distortion also applies. A network configured to strip its own identifying headers is invisible to us, and large customers are the ones who ask for that.

Infrastructure researchers, security teams mapping third-party dependencies and vendors chasing migrations all want the same artefact from this page, and none of them can build it by checking domains one at a time. A per-domain lookup tells you what sits in front of a hostname today. A list tells you which hostnames are still on the platform at all, which is the live question whenever a network is being consolidated onto a successor or wound down. Delivery networks are also bought by hosting providers and agencies as often as by site owners, so the same operator tends to appear across an entire client portfolio at once. Clusters of that shape are invisible domain by domain and obvious the moment you can sort the whole file.
