Dead business websites in Turkey 2026: reachability of 685,343 company web addresses by province and sector

Reachability of 685,343 company web addresses in Turkey, broken down by province (all 81) and sector (40 categories). The base layer is the Overture Maps Foundation places dataset (CDLA-Permissive-2.0), filtered to Turkey. Every business record carrying a website field was requested once; the response (or the failure to get one) is what this dataset records. Provinces were assigned geographically, by intersecting each record's coordinates with official boundaries, because Overture's own address region field is null on roughly 92% of Turkish records. Headline figures 39.6% of the web addresses businesses publish are dead (271,566 of 685,343). Only 413,777 answered. 164,281 hostnames do not resolve at all (24.0%): the domain itself is gone, not merely the page. This is the single largest failure class, larger than every HTTP error combined. The rest: 58,025 returned a 4xx status, 32,729 timed out, 7,924 returned 5xx, 3,236 refused the connection, 2,693 redirected without resolving, 911 were malformed URLs. Sector spread is wide. Car dealers (33.5% reachable), real-estate agents (34.8%) and real-estate firms (39.6%) are the worst; ATMs (95.8%), banks and credit unions (95.4%) and mobile phone stores (82.4%) the best. A regulated balance sheet appears to predict a working website better than being an internet-facing consumer business does. Province spread is narrower than the sector spread but real: Tokat (54.8% reachable), Elâzığ (55.2%) and Van (55.4%) sit at the bottom, well under the 60.4% national average. How to read the failure classes dns_missing is the strongest signal: the hostname has no DNS record, so the domain has lapsed. http_4xx mixes genuinely missing pages (404) with bot blocking (403 accounts for 34,778 of them), so it is a weaker indicator of abandonment. A site counted as reachable answered with a 2xx during the crawl; no judgement is made about its content. Method, province and sector tables and the interactive report: English / Türkçe.
