Facebook Inc. climbed in U.S. premarket trading after an hours-long service outage that the company blamed on a problem with its network configuration.

The stock gained 1.5% to $331.20 at 4:30 a.m. in New York, paring a 4.9% slump Monday tied to the service failure of its main app as well as Instagram and WhatsApp.
