Service Issue Hits Australia Websites, ITnews Reports Inc.’s Web Services arm suffered disruptions on Sunday, knocking out websites for some client companies in Australia, ITnews reported.

A six-hour power failure hit Amazon Web Services in Sydney after severe storms in the area, a company representative told ITnews, an Australian website. Among the firms affected were ticketing company TryBooking, food-delivery service Menulog and personal finance application PocketBook, ITnews said. Sites owned by Fairfax Media, Foxtel and the Daily Telegraph also had interruptions.

A representative for Seattle-based Amazon didn’t immediately respond to requests for comment. Amazon’s cloud business powers websites for a variety of companies. Its service health dashboard showed good performance in the Sydney region as of 11:30 a.m. in New York.

Amazon Web Services is a growing part of the e-commerce giant’s business. The unit generated first-quarter revenue of $2.57 billion, up 64 percent from $1.57 billion a year earlier.
