Internet outages reveal gaps in coverage

FLAGSTAFF, Ariz.

When vandals sliced a fiber-optic cable in the Arizona desert last month, they did more than time-warp thousands of people back to an era before computers, credit cards or even phones. They exposed a glaring vulnerability in the nation’s Internet infrastructure: no backup systems in many places.

Because Internet service is largely unregulated by the federal government and the states, decisions about network reliability are left to service providers. Industry analysts say these companies generally do not build alternative routes, or redundancies, unless they believe it is worthwhile financially.

The result: While most major U.S. metropolitan areas have backup systems, some smaller cities and many rural areas do not.

“The more rural the location, the more likely that there’s only one road in and out of that location,” said Sean Donelan, a former infrastructure security manager in the U.S. Homeland Security Department who now works for a cybersecurity firm. “If someone manages to cut that fiber, you’ll generally see a one- or two- or three-day outage.”

Despite its own warnings about such vulnerabilities two decades ago, the federal government has taken no steps to require Internet companies to have backup systems, even as it has provided billions of dollars in subsidies to expand broadband Internet into unserved areas.

“Our first responsibility is to make sure that people actually have service,” said Agriculture Secretary Tom Vilsack, co-chairman of President Barack Obama’s newly created Broadband Opportunity Council.

In northern Arizona last month, tens of thousands of residents were without Internet service — some for up to 15 hours — after vandals cut through an underground bundle of fiber-optic cables owned by CenturyLink. ATMs went down, stores couldn’t process credit cards and even 911 service was lost.
