One of the largest IT outages in history started with a software update from cyber security firm Crowdstrike. Around the world, hospitals, businesses, news networks (including NBC) were affected when the update rolled out and crashed Microsoft Windows. CNBC’s Phil LeBeau reports from the airport in Wales, where many flights were grounded as airlines grappled with the outage. CNBC’s Steve Kovach explains how one company’s mistake can bring down millions of systems, and Wedbush analyst Dan Ives explains what’s next for the tech sector. The other headline this Friday: Donald Trump has accepted the Republican nomination for President for the third time. CNBC’s Eamon Javers reports from the Republican National Convention on the increasing pressure on President Biden, and pollster Frank Luntz explains the mixed reactions to Donald Trump’s 93 minute speech.
