Microsoft fixes global outage that also hit the Czech Republic

Fact-check index: 62/100 — The core facts about Microsoft's outage and recovery are well supported by the cited Czech sources, but the article's broader claims about infrastructure concentration and Prague's dependence, plus the assertion that Microsoft gave no technical cause, go beyond what the sources state.

• Microsoft said Friday it had fully restored all services after a day-long global outage — Matches both iROZHLAS ('obnovila funkčnost všech svých služeb') and Novinky ('plně obnovil všechny služby').
• Microsoft announced the recovery on X — iROZHLAS states 'Oznámila to v příspěvku na sociální síti X.'
• Nothing indicated the disruption was caused by a cyberattack or artificial intelligence — iROZHLAS: 'nic nenasvědčuje tomu, že by šlo o kybernetický útok nebo počínání umělé inteligence.'
• The outage disrupted households, businesses and government offices worldwide, including in the Czech Republic — iROZHLAS: 'Výpadek zasáhl jak domácnosti, tak firmy a státní úřady, a to po celém světě včetně Česka.'
• Czech users also reported problems during the disruption, per Novinky — Novinky: 'Potíže se týkaly i uživatelů v České republice.'
• Microsoft has not detailed the technical cause of Friday's fault — Neither source discusses a technical cause being given or withheld; absence of mention in these two short reports doesn't confirm Microsoft never detailed it elsewhere.
• The outage illustrates how concentrated digital infrastructure has become in a handful of American firms — This is the article's own analytical framing, not stated or supported by either source.
• Prague, like many capitals, depends on cloud and software services it does not control — Not addressed in either source; an unsupported generalization added by the article.
