The companies at the heart of the outage
As for the companies reported to be at the heart of the outage, their value has dropped but not plummeted.
The company which is said to have launched an antivirus update which apparently sparked the outage, CrowdStrike, saw its share price fall 16.63%.
Microsoft, whose cloud computing system Azure is also reported to be a source of global glitches, has seen its share price drop 2.5% in premarket trading.
How has one company been so impactful on the whole world?
Though many will not have heard of CrowdStrike, the US-listed firm was valued at about $83bn (£64.3bn).
The company detects incoming cyber attacks – while protecting its clients.
They have a 24% share of the cyber security services market. It effectively means a company has a one in four chance of being affected with the IT problems.
Company responses
A Microsoft spokesperson said: “We are aware of an issue affecting a subset of customers. We acknowledge the impact this can have on customers, and we are working to restore services for those still experiencing disruptions as quickly as possible.”
