To, co dnes za\u017e\u00edv\u00e1me, je opak: st\u00e1le rostouc\u00ed centralizace v rukou n\u011bkolika glob\u00e1ln\u00edch provozovatel\u016f infrastruktury, kte\u0159\u00ed ovl\u00e1daj\u00ed cel\u00e1 odv\u011btv\u00ed.

Minul\u00e9 v\u00fdpadky cloudov\u00e9 slu\u017eby Cloudflare a Amazon AWS uk\u00e1zaly, jak rychle se mohou v d\u016fsledku naru\u0161en\u00ed provozu selhat zn\u00e1m\u00e9 komunika\u010dn\u00ed kan\u00e1ly: slu\u017eby zas\u00edl\u00e1n\u00ed zpr\u00e1v, poskytovatel\u00e9 videochatu a soci\u00e1ln\u00ed s\u00edt\u011b se n\u00e1hle stanou nedostupn\u00fdmi.

Decentralizace je v\u0161ak nepraktick\u00e1.
