A problem at Amazon’s cloud computing service disrupted internet use around the world. The outage on Monday took down a broad range of online services, including social media, gaming, food delivery, streaming and financial platforms. Amazon said the outage was resolved as of Monday evening. The all-day disruption and the ensuing exasperation it caused served as the latest reminder that 21st century society is increasingly dependent on just a handful of companies for much of its internet technology, which seems to work reliably until it suddenly breaks down.
