Yahoo! Mail

Yahoo's e-mail crashed yesterday. Thousands of users didn't have access to their emails for hours. It is not clear what the cause of the problem is.

"You may not be able to access some of our services, including email. Our main priority right now is to resolve the issue. We appreciate your patience," a Yahoo customer service team said.

Yahoo confirmed on Jan. 9 that chief executive Marissa Mayer will quit the company's board after its merger with Verizon.

Mayer is expected to remain with Yahoo's core business, which is being bought by the U.S. telecom titan.
 Yahoo is selling its internet operations as a way to separate that from its more valuable stake in Chinese internet giant Alibaba.

BELGRADE - A data breach in August 2013 exposed information held in more than 1 billion Yahoo user accounts, the company said Wednesday.

The hacking incident is separate from an intrusion Yahoo reported in September, when the company disclosed 500 million user accounts were exposed in 2014.

Yahoo Inc said on Sept. 22 that at least 500 million of its accounts were hacked in 2014 by what it believed was a state-sponsored actor, a theft that appeared to be the world's biggest known cyber breach by far. 

Yahoo has begun shutting down some of its digital magazines as the struggling online pioneer's latest reorganization plan.
