Change History
| Date | Change |
|---|---|
| 2026-10-05 | Read the clinic's Google listing on 2026-10-05 (its lowest-rated and newest reviews with the star histogram): the owner replies to reviews; no repeated complaint. |
| 2026-10-02 | Google indexing quality changed from partial to poor: the only search result on a clinic domain is on its former website domain, which now serves unrelated content (checked 2026-10-02). |
| 2026-10-02 | Google indexing quality changed from good to partial after a name-and-city web search on 2026-10-02 (own site first listed at position 6 of 9). |
| 2026-09-30 | Re-read on 2026-09-30: the clinic's former website domain, sonrisaistanbul.com, now shows an unrelated gambling page, so the website and its English version are corrected to absent and the link is removed; dentists' names and fields, which rested only on a directory listing, are now open; prices are now open, as the website read in August 2026 no longer exists and the clinic's Instagram account could not be read in full; services, contacts and address now rest on the clinic's Google listing. |
| 2026-08-26 | Link-rot cleanup round 2 (2026-08-26): re-verified sonrisaistanbul.com — live at the bare root domain (dead s21 /en/ path re-confirmed 404); re-cited hasWebsite/serviceListPublished/clearContacts/englishVersion/addressAndMap/all 7 price-transparency criteria against the live root, and refreshed dedicatedServicePages to false (site restructured to a single-page layout, no per-service pages found, was true). Dropped dead s21 from specializationsListed/offersImplantology/worksWithForeigners/englishSpoken, which remain safely supported by the live Dentavacation listing (s22) alone. offersSurgery (maxillofacial-surgeon claim) could not be re-confirmed on the current homepage and stays cited only by dead s21 — left unresolved, s21 not pruned. SEP RNP cédula lookup (sonrisa-istanbul-doclic) remains network-blocked (ECONNREFUSED, re-confirmed) with no substitute registry found; the 3 named doctors' licenses stay null/unresolved. |
| 2026-08-26 | Link-rot cleanup 2026-08-26: pruning 2 dead source(s) confirmed unreachable in an external-link check (checked 2026-08-26) and re-confirmed dead by direct recheck where applicable. s21 [https://sonrisaistanbul.com/en/]: https://sonrisaistanbul.com/en/ (HTTP 404, rotten) | sonrisa-istanbul-doclic [https://cedulaprofesional.sep.gob.mx/cedula/presidencia/indexAvanzada.action]: https://cedulaprofesional.sep.gob.mx/cedula/presidencia/indexAvanzada.action (attempt1: getaddrinfo EAI_AGAIN cedulaprofesional.sep.gob.mx; attempt2 (+30s): Connect Timeout Error (attempted address: cedulaprofesional.sep.gob.mx:443, timeout: 10000ms), other->stable-dead on recheck) |
| 2026-08-25 | License verification 2026-08-25 against SEP RNP (dentists) and CLUES (clinics): both national registries unreachable from this environment — Sonrisa Istanbul's clinic license and its 3 named doctors' cédulas could not be verified; all left null, none marked false. |
| 2026-08-25 | Re-verification 2026-08-25: the stored URL (sonrisaistanbul.com/en/) now 404s, but the site's root (sonrisaistanbul.com) is live — recorded as the current website; confirmed address, phone unchanged, not permanently closed; Google rating dropped 5.0→4.9 as reviews rose 176→182. |
