Does this page show Cahokia Heights specifically, or the whole county?

Right now, the St. Clair County county-wide view, which covers Cahokia Heights. No utility outage map we follow has yet listed an outage for Cahokia Heights by name; utilities here have so far reported only county-wide totals, or used area names we cannot match to Cahokia Heights. If that changes during an outage, the city's own count and restoration time appear here automatically. East St. Louis (3 mi N) is the closest place we track separately.

How accurate is the restoration estimate?

Every estimate is later graded against when the tracked outage was substantially restored (~90% of customers back), and the track record is published on our accuracy page. Estimates firm up a few hours into an outage once a steady restoration trend appears; very small outages are marked "too small to estimate" rather than guessed.
