On Tuesday last week at 7:30pm, Cloudflare, the world’s largest Internet infrastructure provider offering Web security and traffic acceleration services, had a major crash.
The outage brought down critical online services worldwide, including several essential public and government Web sites in Taiwan, for 45 minutes. The incident was no minor network glitch — it was a serious reminder of digital national security concerns, a global issue Taiwan must be especially alert of.
Having long been a target of Chinese cyberattacks, Taiwan’s dependence on Cloudflare is very risky. The risks include distributed denial-of-service attacks, in which targets are flooded with junk traffic from multiple sources to paralyze the Web site.
