Several websites suffered downtime on Monday owing to a software glitch affecting Juniper routers.
The problem stemmed from a Border Gateway Protocol (BGP) update made to Juniper routers running the JunOS versions 10.2 and 10.3.
The glitch, which caused downtime for hundreds of websites, affected a large number of internet service providers and networking service providers, V3 reports.
Juniper failed to give a detailed statement at that time, but Level3, one of the hosting company's affected by the glitch confirmed what had happened.
"Shortly after 9am Eastern Time, Level 3's network experienced several outages across North America and Europe relating to some of the routers on our network," it said in a statement on its website.
"Our technicians worked quickly to bring systems back online. At this time, all connection issues have been resolved, and we are working hard with our equipment vendors to determine the exact cause of the outage and ensure all systems are stable," the company later informed.
Level3 said that the issue had been resolved at 4:00 PM Monday afternoon and informed that it had started notifying affected customers.
