Around the world, businesses and essential services, including airlines, hospitals, railway networks and television stations, were affected on Friday by a global generation outage that affected Microsoft users.
In many countries, flights have been suspended, staff may simply not use their systems, and in some cases, consumers may simply not make card bills in stores. Although some issues were resolved within hours, many businesses, websites, and airlines continued to struggle to recover.
A series of outages around the world as data screens, connection systems and transmission networks are shut down.
The factor that affected the majority was due to a faulty update from CrowdStrike, an American cybersecurity company, whose systems are intended to protect users against hackers. Microsoft said Friday that it was aware of a factor affecting machines running “CrowdStrike Falcon. “
But Microsoft had also said there had been a previous outage affecting U. S. users of Azure, its on-premise cloud system. Some users would have possibly been affected by both. Although CrowdStrike sent out a patch, some systems were still affected at midday in the United States, as corporations had to perform manual updates to their systems to fix the issue.
George Kurtz, president and CEO of CrowdStrike, said Friday morning that some systems may take some time.
Below is a picture of how a faulty software update crippled the machines.
