Level 3 (NYSE:LVLT) suffered a router glitch Monday that disrupted its service in North America and Europe, the company said.
In the U.S., millions of Time Warner Cable (NYSE:TWC) high-speed Internet customers, and some of its phone customers, were without service for hours. Also affected were BlackBerry subscribers to Research in Motion services.
"Shortly after 9 a.m. ET today, our network experienced temporary service interruptions across North America and Europe apparently due to a router software issue," Level 3 said in a statement. "It has been reported that a similar issue may have affected other carriers as well. Our technicians worked quickly to address the issue and service is now fully restored."
Juniper Networks (NYSE:JNPR), meanwhile, acknowledged the routers in question were theirs, saying they had to be restarted when they crashed while performing a Border Gateway Protocol update. The company said, "This morning, Juniper learned of a Border Gateway Protocol edge router issue that affected a small percentage of customers. A software fix is available, and we've been working with our customers to immediately deploy the fix."
