1. Member States shall ensure that critical entities notify the competent authority, without undue delay, of incidents that significantly disrupt or have the potential to significantly disrupt the provision of essential services. Member States shall ensure that, unless operationally unable to do so, critical entities submit an initial notification no later than 24 hours after becoming aware of an incident, followed, where relevant, by a detailed report no later than one month thereafter. In order to determine the significance of a disruption, the following parameters shall, in particular, be taken into account:

(a) the number and proportion of users affected by the disruption;

(b) the duration of the disruption;

(c) the geographical area affected by the disruption, taking into account whether the area is geographically isolated.

Where an incident has or might have a significant impact on the continuity of the provision of essential services to or in six or more Member States, the competent authorities of the Member States affected by the incident shall notify the Commission of that incident.
