TTL de\u011ferinin \u00f6nemini yorumlay\u0131n.<\/h3>\n\n\n\n

TTL (Ya\u015fam S\u00fcresi), DNS kay\u0131tlar\u0131nda son derece \u00f6nemli bir parametredir ve saniye cinsinden \u00f6l\u00e7\u00fcl\u00fcr. Bu, \u00f6zyinelemeli DNS sunucular\u0131na ve yerel \u00f6nbelle\u011fe, kayd\u0131n ne kadar uzun s\u00fcre \u00f6nbelle\u011fe al\u0131nabilece\u011fini s\u00f6yler. Daha k\u0131sa bir TTL (\u00f6rne\u011fin 300 saniye) ayarlamak, kay\u0131t de\u011fi\u015fikliklerinin d\u00fcnya \u00e7ap\u0131nda daha h\u0131zl\u0131 y\u00fcr\u00fcrl\u00fc\u011fe girmesini sa\u011flar ve s\u0131k de\u011fi\u015fen servisler i\u00e7in uygundur. Daha uzun bir TTL (\u00f6rne\u011fin 86400 saniye, bir g\u00fcn) ayarlamak, yetkili DNS sunucunuza yap\u0131lan sorgu bask\u0131s\u0131n\u0131 azalt\u0131r ve kullan\u0131c\u0131lar\u0131n \u00e7\u00f6z\u00fcm h\u0131z\u0131n\u0131 art\u0131r\u0131r, ancak de\u011fi\u015fikliklerin y\u00fcr\u00fcrl\u00fc\u011fe girmesi daha yava\u015f olur. \u00d6nemli DNS de\u011fi\u015fiklikleri (\u00f6rne\u011fin sunucu ta\u015f\u0131ma) planlanmadan \u00f6nce, ilgili kay\u0131tlar\u0131n TTL'sini d\u00fc\u015f\u00fck bir de\u011fere ayarlamak ve ta\u015f\u0131ma tamamland\u0131ktan ve stabil hale geldikten sonra normal de\u011fere geri d\u00f6nd\u00fcrmek \u00f6nerilir.<\/p>\n\n\n\n

DNS kay\u0131tlar\u0131n\u0131 de\u011fi\u015ftirdikten sonra, neden web sitesine eri\u015fti\u011fimde hala eski sayfa g\u00f6r\u00fcnt\u00fcleniyor?<\/h3>\n\n\n\n

Bu genellikle iki seviyeli \u00f6nbellekten kaynaklan\u0131r. \u00d6ncelikle DNS \u00f6nbelle\u011fi, yerel bilgisayar\u0131n\u0131z veya ISP'nizin DNS \u00e7\u00f6z\u00fcmleyicisi eski IP adreslerini hala \u00f6nbelle\u011fe al\u0131yor olabilir. Yerel DNS \u00f6nbelle\u011fini yenilemeyi deneyebilirsiniz (Windows komut isteminde `ipconfig \/flushdns`'i, macOS\/Linux terminalinde `sudo dscacheutil -flushcache`'i veya `sudo systemd-resolve --flush-caches`'i kullanarak, \u00f6zel komutlar sisteme g\u00f6re de\u011fi\u015fir).<\/p>\n\n\n\n

Sonras\u0131nda taray\u0131c\u0131 \u00f6nbelle\u011fi ve web sitesi sunucusu\/CDN \u00f6nbelle\u011fi gelir. DNS analizi yeni IP'ye do\u011fru \u015fekilde y\u00f6nlendirse bile, taray\u0131c\u0131 eski sayfa i\u00e7eri\u011fini \u00f6nbelle\u011fe alm\u0131\u015f olabilir veya yeni sunucudaki \u00f6nbellek kurallar\u0131 eski i\u00e7eri\u011fin ge\u00e7ici olarak sa\u011flanmas\u0131na neden olmu\u015f olabilir. Taray\u0131c\u0131y\u0131 zorla yenilemeyi (Ctrl+F5) veya taray\u0131c\u0131 \u00f6nbelle\u011fini temizlemeyi deneyin.<\/p>\n\n\n\n

Bunlara daha y\u00fcksek sorgu performans\u0131 ve i\u015fleme kapasitesi (QPS), daha ayr\u0131nt\u0131l\u0131 analiz raporlar\u0131, co\u011frafi konuma dayal\u0131 ak\u0131ll\u0131 analiz (GeoDNS), daha g\u00fc\u00e7l\u00fc API deste\u011fi, m\u00fc\u015fteri hizmeti deste\u011fi ve daha y\u00fcksek servis d\u00fczeyi anla\u015fmas\u0131 (SLA) garantileri, mesela ,991 uptime gibi dahildir.<\/p>\n\n\n\n
