The resilience of a system that depends on the grid can be read on four constructs: how much of the grid's failure reaches it, how long it withstands the outage, whether it recovers before the grid and by what means, and whether any of that has changed across storms. The grid below shows the two lifelines the paper measures, wastewater and cellular, on all four, every cell drawn live from the county-windows of the nine hurricanes. Select storms in the strip to redraw on a subset.

The models' estimates (the incidence-rate ratios, odds ratios and era slopes) are those of the paper and do not refit when storms are removed; the counts, shares and histograms do. Open circles are the silent county-windows.
