A major Cloudflare outage on Tuesday disrupted access to many websites worldwide after a sudden surge in traffic caused errors across parts of its network. The company said services were gradually recovering but the cause is still being investigated. Experts noted the incident highlights how much of the internet depends on a small number of infrastructure providers, making widespread ripple effects likely when one goes down.
