Yahoo said Wednesday it was encrypting traffic flowing between its data centers, several months after leaked documents revealed the government had been sniffing those links.
Traffic moving between Yahoo data centers is fully encrypted as of March 31, the company announced on its Tumblr blog. Last October, documents provided by former U.S. National Security Agency contractor Edward Snowden said the NSA had penetrated the main communications links that connect Yahoo and Google’s data centers.
Though it comes after those revelations, the encrypted data links is in keeping with a previous promise by CEO Marissa Mayer to encrypt all information between its data centers by the end of March.
Yahoo said Wednesday that it had also turned on encryption for a range of other services. For one, encryption of mail between its servers and other mail providers that support the SMTPLS standard was enabled in the last month, the company said. Yahoo only just turned on encryption by default between users and its email service in January.
Yahoo said its homepage and all search queries that run on it and most other Yahoo properties now also have HTTPS encryption enabled by default.
But if users want an encrypted session for Yahoo News, Yahoo Sports, Yahoo Finance or Good Morning America on Yahoo, they must manually type “https” into the site’s URL on their browsers, Yahoo said.
