Fail\u00adover ist ein Prin\u00adzip, bei dem auto\u00adma\u00adtisch auf einen Ersatz\u00addienst umge\u00adschal\u00adtet wird, wenn der Haupt\u00addienst nicht mehr ver\u00adf\u00fcg\u00adbar ist.<\/p>\n\n\n\n

Auf das DNS ange\u00adwandt, besteht der Fail\u00adover-Dienst dar\u00adin, DNS-Ein\u00adtr\u00e4\u00adge zu \u00fcber\u00adwa\u00adchen und auf einen Back\u00adup-Ein\u00adtrag umzu\u00adschal\u00adten, falls der Haupt\u00adein\u00adtrag nicht mehr ver\u00adf\u00fcg\u00adbar ist. W\u00e4h\u00adrend des Fail\u00adovers wird der Haupt\u00adein\u00adtrag wei\u00adter\u00adhin \u00fcber\u00adwacht. Sobald die\u00adser wie\u00adder ver\u00adf\u00fcg\u00adbar ist, wird ein Fail\u00adover zum Nor\u00admal\u00adzu\u00adstand durch\u00adge\u00adf\u00fchrt.<\/p>\n\n\n\n

Die \u00dcber\u00adwa\u00adchung wird von einer Rei\u00adhe von Son\u00adden betrie\u00adben, die \u00fcber ver\u00adschie\u00adde\u00adne Netz\u00adwer\u00adke und glo\u00adba\u00adle geo\u00adgra\u00adfi\u00adsche Lagen ver\u00adteilt sind. Die Fail\u00adover-Regeln wer\u00adden im Vor\u00adfeld fest\u00adge\u00adlegt, sei es eine Anzahl von Ite\u00adra\u00adtio\u00adnen oder ein Zeit\u00adin\u00adter\u00advall zwi\u00adschen den Ver\u00adf\u00fcg\u00adbar\u00adkeits\u00adpr\u00fc\u00adfun\u00adgen. Der Kun\u00adde wird \u00fcber den Fail\u00adover mit einer Alarm-E-Mail infor\u00admiert, er wird auch \u00fcber die R\u00fcck\u00adkehr zum Nor\u00admal\u00adbe\u00adtrieb infor\u00admiert.<\/p>\n\n\n\n
