Yahoo’s U.K. unit was fined 250,000 pounds ($334,500) by a British regulator for failing to keep the data of more than half a million users in the country safe from a cyber-attack in 2014.

The decision on Tuesday comes less than a week after the Irish privacy watchdog, which is the lead authority for Yahoo in Europe, ordered the company to make “specified and mandatory” changes in the wake of one of the “biggest data breaches in history.” The U.K. Information Commissioner’s Office said Tuesday that the incident exposed the personal data of approximately 500 million international users of Yahoo’s services.
