Accidental dig-ins cause $50-100B in annual US underground utility damage

Buried fiber optic cables have no inherent protection against excavation equipment, and despite the 811 'call before you dig' system, accidental dig-ins remain the single most common cause of fiber cuts. The core issue is that existing underground utility location records are frequently inaccurate -- cables drift from their documented positions over decades, as-built records were never created or were lost, and private utilities (campus networks, fiber laterals) are often not in the 811 database at all. So what? A single backhoe strike on a fiber trunk can sever thousands of connections simultaneously, causing outages lasting hours to days. Research estimates underground utility damage costs the US economy $50 to $100 billion annually in direct repair costs, service disruption, emergency response, and downstream business losses. For fiber specifically, a single trunk repair can cost $50,000-$250,000 and take 12-48 hours. The problem persists because there is no national registry of underground infrastructure with verified GPS coordinates -- the 811 system relies on each utility voluntarily maintaining its own records, with no standardized format, no accuracy requirements, and no audit.
