On the evening of March 2, 2026, a power outage occurred in Aachen. The outage affected a data center belonging to the municipal IT service provider regio iT. Many authorities in North Rhine-Westphalia lost access to their central IT systems as a result. The critical risk factor lay in the shared dependence of numerous municipalities on a single provider, which caused the disruption to spread throughout the state. The consequences were immediate: numerous public appointments were canceled on March 3, and service portals and specialized applications were only partially functional. (focus: 03.03.26)
Affected authorities – where operations were disrupted
In addition to the city of Aachen, several municipalities and districts in North Rhine-Westphalia reported outages. Among those mentioned were Bielefeld, Düren, Erkelenz, and Würselen. The Rhein-Erft district, the Soest district, the Ennepe-Ruhr district, the Heinsberg district, and the Euskirchen district were also affected. The disruption spread because many of the authorities’ IT systems are centrally provided via regio iT.
Public-facing departments were particularly hard hit. Citizen service centers, vehicle registration offices, lost and found offices, and digital service portals were brought to a standstill. Appointments often couldn’t be kept because applications for identification, case processing, and document creation were unreliable. Some notices were posted on the administrative websites, as these sites remained partially accessible.
An outage of this kind doesn’t just stop online forms. It also impacts internal processes when interfaces and databases are missing. Processes then remain incomplete because verification routines, payment systems, or printing processes fail to run. This creates a backlog that measurably slows down daily operations.
Duration of the disruption and system restart
On Tuesday, March 3, regio iT assessed the situation pessimistically. At that time, “productive operation” was no longer possible. The affected municipalities in North Rhine-Westphalia canceled appointments because they couldn’t properly document services without specialized systems. Simultaneously, the service provider announced that it was working “at full speed” to resolve the issue.
On Wednesday morning, March 4th, the systems were largely back online. The restart was gradual because dependencies between services had to be individually checked. Some functions may still experience glitches, as not every application starts up reliably immediately. Nevertheless, the outcome was clear for citizens: the acute phase was over, but the workload had shifted.
Consequences for Citizens and Municipal Processes After the Outage
Cancelled appointments had to be rescheduled. This ties up staff, as many matters can only be handled in person or within specific time slots. Several administrative offices experienced a backlog of applications because Tuesday was only partially available as a workday. This increased the pressure on the following days.
Even after the system stabilized, organizational work remained. Municipalities had to review which files were open or damaged. This follow-up work consumes resources because every file must remain traceable. The authorities thus faced a dual challenge: ensuring day-to-day operations while simultaneously reducing the backlog.
