People is the count the filing gives, residents of the state unless marked total. Days to notice runs from the discovery date the letter states, or from the end of the breach window when no letter states one, to the date on the state's first record of the incident. "Over" marks a count past the days the state's statute allows for notice to residents. The statute's trigger is a question of fact, the days are arithmetic.
Notice timing, state by state
- 21 days from the end of the breach window (Sep 9, 2021, no discovery date in the letter) to the Delaware record (Sep 30, 2021). Statute: 60 days from determination of the breach (6 Del. C. § 12B-102).
The statutes
- Delaware: 60 days to notify residents from determination of the breach, 6 Del. C. § 12B-102. Attorney General when more than 500 Delaware residents are affected, no later than the resident notice.
