Whois is not considered authoritative for registered domain objects. The Whois service may be scheduled for downtime during production or OT&E maintenance periods. Queries to the Whois services are throttled. If too many queries are received from a single IP address within a specified time, the service will begin to reject further queries for a period of time to prevent disruption of Whois service access.

About Chicago Boss

Erlang came out of telephone switching, where processes crash constantly and the system is not permitted to notice, and for a while several people tried to carry that reliability model into ordinary web development. Chicago Boss was one of those attempts. Written in Erlang, released under the MIT license by Evan Miller, with a first public version in 2010, it took the shape of the frameworks web developers already knew: model view controller, Django style templates, URL routing, an object mapper spanning several databases, sessions, mail and internationalisation, plus fully asynchronous network handling that made long lived connections cheap rather than exotic.

Adopting a framework like that said more about the team than about the site. Nobody arrives at an Erlang web framework by browsing beginner tutorials. A team already had operators comfortable with the runtime, or a product whose concurrency requirements made the runtime worth the hiring problem, and putting a familiar shaped layer on top was a way of making that choice survivable for the developers who had to work inside it. The audience this framework was aimed at largely moved to Elixir and its own web framework, which offered the same runtime with a friendlier surface, so the deployments that remain tend to be older systems looked after by the people who built them.

Back end frameworks are a hard class of technology to detect, and being honest about that matters more than any figure attached to it. A server side framework is visible only when it advertises itself: a response header, a cookie name, a session format, a default error page, a URL convention. A reverse proxy, a delivery network or a tightened header policy can remove every one of those without a line of application code changing. As of October 2026 our count for this fingerprint stands at 1, and the correct reading is sites that still leak an identifiable signature, rather than sites running the framework.

The detection gap is exactly why a compiled list beats guessing. A per domain lookup confirms a hunch about one host. A list of every domain where the signature survives is a roster of long running installations on this runtime, which is what you want if you sell maintenance for it, if you study how framework populations age and disappear, or if you are looking for systems whose owners have a migration problem they have not scheduled yet.
