# Postmortem â IndisponibilitĂ© des rĂ©sultats de recherche ## RĂ©sumĂ© Le 17 aoĂ»t 2026, entre 15 h 36 et 17 h 15 CEST, un incident a affectĂ© le service de recherche et certaines fonctionnalitĂ©s dâanalyse. Durant cette pĂ©riode, les requĂȘtes adressĂ©es au moteur de recherche Ă©chouaient et les interfaces concernĂ©es ne retournaient aucun rĂ©sultat. Lâincident a Ă©tĂ© dĂ©tectĂ© Ă la suite de signalements du client. Les Ă©quipes techniques ont identifiĂ© une incompatibilitĂ© introduite lors de la mise Ă jour dâune dĂ©pendance logicielle, puis dĂ©ployĂ© une correction. Le service a Ă©tĂ© entiĂšrement rĂ©tabli Ă 17 h 15 CEST. ## Chronologie des Ă©vĂ©nements * **17 aoĂ»t 2026 Ă 15 h 36 CEST** : dĂ©but de lâincident. Les requĂȘtes adressĂ©es au moteur de recherche commencent Ă Ă©chouer. * **Ă partir de 15 h 36 CEST** : lâabsence de rĂ©sultats devient visible dans les interfaces concernĂ©es et fait lâobjet de signalements du client. * **16 h 26 CEST** : les Ă©quipes techniques prennent en charge lâincident et lancent les investigations. * **17 h 08 CEST** : les Ă©quipes techniques dĂ©ploient une premiĂšre correction. * **17 h 13 CEST** : le dĂ©ploiement est terminĂ© et les tests confirment le rĂ©tablissement du fonctionnement attendu. * **17 h 15 CEST** : la correction est mise en production et lâincident est dĂ©clarĂ© rĂ©solu. La durĂ©e totale de lâincident a Ă©tĂ© de **1 heure et 39 minutes**. ## DifficultĂ©s rencontrĂ©es Lâincident rĂ©sultait dâun effet indirect liĂ© Ă lâĂ©volution dâune dĂ©pendance partagĂ©e entre plusieurs composants logiciels. La modification nâaffectait pas directement la logique mĂ©tier du moteur de recherche. Elle concernait une option technique de connexion devenue incompatible avec le client HTTP dĂ©sormais utilisĂ©. Cette incompatibilitĂ© a rendu lâorigine de lâincident moins immĂ©diatement identifiable. Par ailleurs, lâincident a dâabord Ă©tĂ© dĂ©tectĂ© grĂące aux signalements du client et Ă lâabsence visible de rĂ©sultats dans les interfaces. ## Cause de lâincident Une mise Ă jour de dĂ©pendances a entraĂźnĂ© lâutilisation dâun nouveau client HTTP par le composant chargĂ© de communiquer avec le moteur de recherche. Les composants de recherche et dâanalyse lui transmettaient encore une option de dĂ©lai de connexion propre Ă lâancien client HTTP. Cette option nâĂ©tant pas reconnue par le nouveau composant, les appels au moteur de recherche Ă©chouaient systĂ©matiquement. La correction a consistĂ© Ă remplacer cette option par son Ă©quivalent compatible avec le nouveau client HTTP. Ce changement ne modifie pas le comportement fonctionnel du service : il maintient uniquement la limite prĂ©vue pour lâĂ©tablissement de la connexion au moteur de recherche. ## Perte de donnĂ©es Aucune perte ni altĂ©ration de donnĂ©es nâa Ă©tĂ© constatĂ©e. Pendant lâincident, les donnĂ©es sont restĂ©es enregistrĂ©es, mais les fonctionnalitĂ©s affectĂ©es ne permettaient plus de les retrouver ou de les afficher correctement dans les rĂ©sultats de recherche et dâanalyse. ## Mesures de remĂ©diation Les Ă©quipes techniques ont mis en Ćuvre les actions suivantes : * correction de lâoption de connexion utilisĂ©e par les composants de recherche et dâanalyse ; * dĂ©ploiement et validation de la correction sur les diffĂ©rents composants concernĂ©s ; * vĂ©rification du rĂ©tablissement des rĂ©sultats de recherche aprĂšs la mise en production. --- # Post-mortem â Search results unavailable ## Summary On 17 August 2026, between 15:36 and 17:15 CEST, an incident affected the search service and certain analytics features. During this period, queries sent to the search engine failed and the affected interfaces returned no results. The incident was detected following reports from the client. The technical teams identified an incompatibility introduced during the update of a software dependency and subsequently deployed a fix. The service was fully restored at 17:15 CEST. ## Timeline of events * **17 August 2026 at 15:36 CEST**: start of the incident. Requests sent to the search engine began to fail. * **From 15:36 CEST**: the absence of results became apparent in the affected interfaces and was reported by customers. * **16:26 CEST**: the technical teams took charge of the incident and began investigations. * **17:08 CEST**: the technical teams deploy an initial fix. * **17:13 CEST**: the deployment is complete and tests confirm that the system is functioning as expected. * **17:15 CEST**: the fix is put into production and the incident is declared resolved. The total duration of the incident was **1 hour and 39 minutes**. ## Challenges encountered The incident resulted from an indirect effect linked to a change in a dependency shared between several software components. The change did not directly affect the search engineâs business logic. It concerned a technical connection option that had become incompatible with the HTTP client now in use. This incompatibility made the cause of the incident less immediately identifiable. Furthermore, the incident was first detected thanks to reports from users and the visible absence of results in the user interfaces. ## Cause of the incident An update to dependencies led to the component responsible for communicating with the search engine using a new HTTP client. The search and analysis components were still passing it a connection timeout option specific to the old HTTP client. As this option was not recognised by the new component, calls to the search engine consistently failed. The fix involved replacing this option with its equivalent, which is compatible with the new HTTP client. This change does not alter the functional behaviour of the service: it merely maintains the intended limit for establishing the connection to the search engine. ## Data loss No data loss or corruption was observed. During the incident, the data remained stored, but the affected functionalities were no longer able to retrieve it or display it correctly in the search and analysis results. ## Remedial measures The technical teams implemented the following actions: * correction of the connection option used by the search and analysis components; * deployment and validation of the correction across the various components concerned; * verification that search results had been restored following the production roll-out.
