SYDNEY—Websites of dozens of financial institutions and airlines in Australia and the United States were briefly hit by an internet outage on Thursday, after a second major blackout in little more than a week.
The Australian outage, which also affected the country’s central bank, was caused by glitches on the servers of Akamai, an operator of content delivery network (CDN) services used in speeding up the delivery of data-heavy content, videos and games to web pages.
