Klaviyo driftsforstyrrelser

1. 27. august 2026 kl. 00.09 UTCinvestigating

   Klokken 15: 25 US / Eastern den 26 august 2026, begyndte vi at opleve et problem, hvor nogle profiler ikke skrider frem tidligere tid forsinkelse handlinger i strømme som forventet. Dette påvirker flow sende på tværs af alle messaging kanaler, herunder e-mail, tekst messaging, skubbe, og WhatsApp. Meddelelser, der sendes fra kampagner, og strømme, der ikke omfatter tidsforsinkelser handlinger er ikke påvirket. Vi arbejder aktivt på et fix. Vi vil fortsætte med at levere opdateringer, efterhånden som flere oplysninger bliver tilgængelige.

2. 27. august 2026 kl. 01.15 UTCidentified

   Vores Engineering team har identificeret årsagen til dette problem og arbejder på at gennemføre en rettelse for at løse den resterende indvirkning på at sende for strømme, der er påvirket af tidsforsinkelsen problem. Når fixet er rullet ud, vil vi gennemgå og reparere enhver påvirket strømme. Vi arbejder på at løse dette så hurtigt som muligt og vil dele en anden opdatering om kort tid.

3. 27. august 2026 kl. 01.51 UTCmonitoring

   Fra 9: 30 PM US / Eastern, strømme er genoptaget sende som forventet på tværs af alle berørte messaging kanaler. Vi er i gang med at behandle de berørte flowmeddelelser. Et fix er blevet installeret, og systemets ydeevne forbedres. Vi fortsætter med at overvåge nøje og værdsætter din tålmodighed under denne hændelse.

4. 27. august 2026 kl. 03.42 UTCresolved

   Fra 11: 26 PM US / Eastern den 26 august 2026, reparation til at behandle berørte flow meddelelser fra vinduet af indvirkning er blevet afsluttet, og flow afsendelse er genoptaget som forventet på tværs af alle kanaler. Vi undskylder forstyrrelsen. Denne hændelse er blevet løst.

1. 19. august 2026 kl. 17.15 UTCidentified

   Vi oplever i øjeblikket forsinkelser på op til ca. 3 timer i, hvor hurtigt nylige profilopdateringer afspejles i realtidssegmenter. Det betyder, at ændringer i profiler kan tage længere tid end normalt at opdatere segmentmedlemskab, hvilket kan påvirke segmentbaseret målretning. E-mail og SMS-afsendelse og andre centrale funktioner fungerer normalt. Vi arbejder aktivt på at løse dette og vil dele endnu en opdatering, så snart vi har flere oplysninger.

2. 19. august 2026 kl. 18.13 UTCmonitoring

   Et fix er blevet installeret, og systemets ydeevne forbedres. Nylige profilopdateringer afspejles nu hurtigere i realtidssegmenter, og forsinkelsen er forbedret til ca. 2,5 timer. Ændringer af profiler kan stadig tage lidt længere tid end normalt at opdatere segment medlemskab som systemet fortsætter med at indhente. E-mail og SMS-afsendelse og andre centrale funktioner forbliver upåvirket. Vi fortsætter med at overvåge nøje og værdsætter din tålmodighed under denne hændelse.

3. 19. august 2026 kl. 18.38 UTCresolved

   Profilopdateringer afspejles nu i realtidssegmenter ved normal hastighed. Eventuelle profilændringer i egenskaberne under hændelsesvinduet er blevet afspejlet i segmentmedlemskab som forventet, og der kræves ingen handling fra din side. Denne hændelse er blevet løst.

   Begynder omkring 8: 09 AM US / Eastern den 23 juli 2026, profil import startede gennem API, CSV upload, eller SFTP kan undlade at fuldføre, og de importerede profiler kan ikke oprettes. Nye integreringer forbundet i denne periode kan også blive forsinket i starten af deres oprindelige synkronisering. Vi har identificeret årsagen og er ved at iværksætte et fix. Vi arbejder på at løse dette så hurtigt som muligt og vil dele en anden opdatering om kort tid.

2. 23. juli 2026 kl. 15.16 UTCmonitoring

   Profilimport har genvundet, og import gennem API, CSV upload, eller SFTP er forarbejdning normalt igen. Integrationer, der er forbundet under anslagsvinduet, genoptager også deres oprindelige synkronikker. Vores team arbejder på at genbehandle API import, der mislykkedes under hændelsen. Vi fortsætter med at overvåge nøje og værdsætter din tålmodighed under denne hændelse.

3. 23. juli 2026 kl. 16.01 UTCresolved

   Systemet forbliver stabilt, og import gennem API, CSV upload, eller SFTP er behandling normalt. Import, der mislykkedes under hændelsen, blev ikke automatisk genbehandlet. Hvis en import du startede mellem 8: 00 og 11: 00 US / Eastern den 23. juli 2026 ikke gennemført, bedes du køre den igen for at sikre, at disse profiler er importeret. Denne hændelse er blevet løst.

1. 9. juli 2026 kl. 01.52 UTCinvestigating

   Klokken 4: 00 US / Eastern den 8. juli 2026, vi identificerede forsinkelser synkronisere produktopdateringer fra integrations ved hjælp af webkroge. Dette forårsager katalog data, herunder i Skabeloner og Kundehub, ikke opdatere i realtid. Kunden kan se, at produktdata er forældede med op til 4 timer. Afsendelse er ikke påvirket, men produktdataene i skabeloner afspejler muligvis ikke realtidsoplysninger. Vi arbejder på at løse dette så hurtigt som muligt og vil dele en anden opdatering om kort tid.

2. 9. juli 2026 kl. 03.14 UTCidentified

   Fra 9: 45 PM US / Eastern den 8 juli 2026, vi holdt pause behandling af nye webkroge til produktkataloger, mens vi fortsætter med at arbejde på et fix. Katalogdata, herunder i Skabeloner og Customer Hub, vil forblive forældede, indtil synkroniseringen genoptages. Vores engineering team arbejder aktivt på at genoprette realtime katalog opdateringer. Vi vil give opdateringer, så snart mere information er tilgængelig.

3. 9. juli 2026 kl. 04.34 UTCmonitoring

   Fra 11: 13 PM US / Eastern den 8. juli 2026, vi er genoptaget behandling af webkroge. Det betyder, at alle nye webkroge fra integreringer, som bruger webkroge til at opdatere produkter, nu synkroniseres i realtid. Vores Engineering Team arbejder med at implementere en reparation for at indhente på enhver produktopdatering webkroge fra under vinduet af kollision (9: 45 PM og 11: 13 PM US / Eastern juli 8, 2026). Vi bekræfter det, når reparationen er afsluttet, og hændelsen er afsluttet.

4. 9. juli 2026 kl. 16.13 UTCmonitoring

   Produktopdateringer fra e-handel-integration fortsætter med at synkronisere normalt i realtid.
