Jist\u011b jste si v\u0161imli, \u017ee jsme se dostali do mal\u00e9ho skluzu v na\u0161em harmonogramu a v posledn\u00edch dnech se v datacentru ani na webu nic nem\u011bnilo. Co n\u00e1s tedy \u010dek\u00e1 v dal\u0161\u00edch dnech a kde je probl\u00e9m?<\/p>\n\n\n\n\n\n\n\n

Vzhledem k tomu, \u017ee v prvn\u00ed f\u00e1zi budeme provozovat v na\u0161em datacentru WEDOS jen „p\u00e1r server\u016f“, tak pojedou jen z UPS, kter\u00e1 by m\u011bla ut\u00e1hnout des\u00edtky server\u016f cca 2 hodiny. Na\u0161e datacentrum je cca 3km od nejv\u011bt\u0161\u00ed jiho\u010desk\u00e9 rozvodny, a tak del\u0161\u00ed v\u00fdpadek (m\u016f\u017ee samoz\u0159ejm\u011b nastat) je velice nepravd\u011bpodobn\u00fd.
