Jackson Electric Co-Op Sees 30% Work-from-Home Internet Surge

When the coronavirus crisis forced the shutdown of America, Jackson Electric Cooperative turned it up. Broadband Internet became a lifeline for the residents of Matagorda Bay, Texas, in the U.S., with miles of Gulf Coast beaches and fresh oysters, blue crab, and shrimp. Jackson Electric’s smart community network, built on a foundation of Juniper routing, easily handled a 30% surge in Internet traffic and a 130% spike in subscriber connections.
