tova i mnogo hora se uchudvat zashto VeriSign sa pusnali zapis s tolkova
malko vreme na cache zhivot (samo 15 min). Obiknoveno zapisi s talyv
malyk TTL sa chesto smeniashti se. I ako naistina VeriSign iskat da smeniat
chesto tozi zapis sme izpraveni pred dosta seriozno predizvikatelstvo.
Registriraneto na nov domain niama nishto obshto s TTL. Ne byrkaite neshtata.
To mozhe da ima obshto s opresniavane na informaciata. Naprimer, neka niakoi
da e promenil dannite za domaina si. Ako nikoi server za imena e zapital za
zapisi za tozi domain malko predi registera da pusne promenite, toi shte
cache-ira starite zapisi. Sledovatelno v/u tozi DNS server starite zapisi shte
se paziat do iztichane na vremeto im na zivot i novite niama da se vizhdat
(govorim za vidimost ot servera, koito gi e cache-iral). Vsichki clienti,
koito pitat vyprosnia server za imena syshto shte poluchavat starite zapisi.
Molba: Haide da ne se izkazvame nepodgotveni!
