Expired domains in industry and equipment

Throughout its history (2011–2022), the site represented a single Japanese company based in Nagoya, specializing in planning, graphic design, and web production. No niche changes occurred.

Throughout its history (2000–2023), the domain hosted a company site producing promotional and souvenir items (badges, medals, commemorative coins, costume jewelry) via centrifugal casting. The niche remained unchanged; the final version fully matches the original.

The domain consistently held a single niche (ANTENNA DESIGN — antenna manufacturing) from 2001 to 2018 with no changes. The final niche before the drop matches the niche that built the entire link profile — a positive signal.

History is unstable: 2003–2005 — a Chinese site of unclear niche (likely a portal/catalog, titles in broken encoding); 2010–2012 — a placeholder with the domain name; 2013 — a domain sale/transfer page with QQ; since 2022 — a Chinese site about band saw machines (青岛晨龙锯床). The final niche most likely does not match the niche that built the main link profile.

Originally the domain was in Chinese with an unreadable page title (likely characters in the wrong encoding), then in 2012 it switched to a site for the Chinese company "航天绿电" (Aerospace Green Electric), focused on electromagnetic compatibility equipment and power quality, and kept that focus until 2017.

The domain was long used (2013–2021) as the site of a manufacturer of explosion-proof storage units (炸药库,雷管箱), then in 2022 shifted to gun storage equipment (枪柜,弹药柜); the final state before the drop was a blank page with no title.

Consistent niche — metalworking and machine shop production (D-3B0F91 CZ s.r.o.) — traceable from 2015 through the final state in 2019 with no change.

A stable site of a real industrial company (D-B1E3A5 Co., Ltd., Thailand) from 2007 to ~2022 with no niche changes. After the drop, the domain was taken over and now hosts a Chinese online casino.

Stable niche — the site of the Czech company D-5E3278 s.r.o. (likely medical equipment or services) with no niche change throughout its history.

Stable niche — coffee equipment (ES-250 K coffee maker), no niche changes throughout its history.

From 2000 to 2006, the site was dedicated to the Italian dental equipment manufacturer (D-E68FC2). From 2007 onward, the niche disappeared, the site turned into a blank page with the domain name as the page title, and then went through a series of redirects and downtime.

From 2005 to 2021 — a stable Italian site focused on aluminum windows, doors, and shutters. In 2022, there was a one-time abrupt shift to English-language spam about mining equipment (dolomite mining crusher), which does not match the accumulated link profile.

From 2013 to 2021, the site consistently focused on heat pumps (Isı Pompası) in Turkish. In 2024, the niche abruptly shifted to Vietnamese spam content unrelated to the original niche.

Throughout its history (2020–2025), the site maintained a single niche — industrial pumps for desulfurization and slurry pumps (B2B). No niche change was recorded.

Consistent niche of laboratory equipment and consumables (Petri dishes, test tubes) throughout the site's active life from 2010 to 2018. No niche changes recorded.

A stable Czech niche of 'saunas, manufacturing, sales' that persisted throughout the site's active life from 2016 to 2019. No niche changes were recorded.

No niche change: throughout its history (2001–2013), the domain was used as a company site selling equipment for hydrogeological and engineering-geological surveys (samplers, filters, packers).

Stable narrow B2B niche since 2001: manufacturing of components for electrical and automotive industries, refined in 2022 as "specialist in plastic injection molding and assembly work". No niche changes recorded.

Initially the domain was used for spam (music/phones), then from 2014 to 2025 it was consistently the site of a company renting sound and lighting equipment in Antalya (Turkey). In 2025 the niche abruptly shifted to Chinese (empty page title "首页title"), which does not match the accumulated link profile.

Early history (2021) contains no content — empty page title, then "Suspended Domain." Since May 2024, the domain has been restored as a live site in Vietnamese about the production of steel structures and roofing materials ("Nhà máy tôn xà gồ Nice House"), and the niche is stable.
