Restrictions in the transmission and publication of reporting data are referred to as technical status messages. In this context, it is differentiated between incidents and maintenance windows. Incidents and maintenance windows are published forthwith.

Incidents: Unplanned events on the part of the reporting company, which lead to flawed reporting data or missing reporting data which is therefore published with a delay, are referred to as incidents. The reasons for such include, in particular, IT-technology malfunctions during the submission of the message or in exceptional circumstances malfunctions during the processing of the message.

Maintenance Windows: Scheduled maintenance activities, which – usually temporarily – cause incomplete reporting data and/or reporting data which is published too late, are referred to as Maintenance Windows. Maintenance Windows are scheduled activities for the purpose of IT system adjustments, which can take place both on the part of the reporting company and on the part of EEX.
