Where this data comes from
Numbers on this page come from National Grid — Massachusetts's public outage data — the same data behind its official outage map — collected on a rotating cycle (each utility typically refreshes within the hour; the card above shows exactly when these numbers were last collected). When the utility posts a restoration time we show it as the official estimate; our independent estimate is computed from the outage's own recovery trend and graded publicly. Coverage and level of detail vary by utility: some break out towns and neighborhoods, others publish only county or area totals.
Not affiliated with National Grid — Massachusetts. Report outages and downed lines to the utility directly via its official outage site ↗ — never rely on this page for emergencies.
