BOSTON (AP) — A software bug at a major network provider briefly knocked dozens of financial institutions, airlines and other companies across the globe offline during peak business hours in Asia.

Akamai, which runs one of the internet’s main content-delivery systems, said the outage Thursday was not caused by a cyberattack, but rather a software bug on a service that protects customers against denial-of-service attacks.
