MasterCard Says Website Faltered Amid Internet-Service Outage

MasterCard Inc., the world’s second-biggest consumer-payments network, said it lost service on its website today because of a failure at an Internet service provider.

The site was restored after a “telecommunications/Internet Service Provider outage that impacted multiple companies, including ours,” James Issokson, a spokesman for MasterCard, said in an e-mail after he was asked whether hackers were responsible. “It is important to note that no cardholder data has been impacted and that cardholders can continue to use their cards securely.”
