For a little more than 90 minutes yesterday, internet service for millions of users in the U.S. and around the world slowed to a crawl. Was this widespread service degradation caused by the latest botnet threat? Not this time. The cause was yet another BGP routing leak — a router misconfiguration directing internet traffic from its intended path to somewhere else.
On Nov. 6, our network experienced a disruption affecting some IP customers due to a configuration error. All are restored.
