# Universitätsrechenzentrum (URZ)

The **Universitätsrechenzentrum (URZ)** is the central provider of information and communication technology (ICT) services for the [[universitat-greifswald]] and its associated scientific institutions. It manages the overarching [[campus-it]] infrastructure and environment, ensuring that students, researchers, and staff have access to necessary digital tools and connectivity.

## Organizational Structure
The URZ is organized hierarchically under a **Director**. The structure is divided into technical and administrative branches:
- **Technical Operations**: Managed by the **Technische Leitung**, covering networks, communication, basic services, and applications.
- **Business Operations**: Managed by the **Geschäftsführung**, covering administration and general services.
- **High Performance Computing**: The [[hpc-brain-cluster]] unit reports directly to the Director.

Detailed information on the hierarchy can be found in [[urz-organisationsstruktur]].

## Strategic Role and Responsibilities
The URZ is responsible for the operation and maintenance of central services, including account management, network infrastructure, and various software platforms used across the university.

## Support and Transparency

The URZ provides problem-oriented consulting and technical support for all Campus-IT (central services) problems, including its web services, utilizing centralized [[urz-support-channels]]. It is also responsible for the documentation and provision of instructions for a wide array of services, including identity management, network security, and digital teaching tools.

### Support Channels
The structure of support is described across source versions as follows:

- **Existing Version:**
    - **Telephone Support:** A dedicated hotline available at extension **1420**.
    - **Digital Support:** Managed via a [[ticketsystem]] integrated into/hosted on the [[groupware]] platform.
    - **Additional Context:** The [[groupware-ticketsystem]] is noted as the primary method to optimize request processing, while the hotline (ext. **1420**) serves as a secondary method.

- **Newly Generated Version:**
    - **Ticket System:** The primary method for contacting support, hosted within the [[groupware]] environment (see [[groupware-ticketsystem-usage]]).
    - **Hotline:** Direct telephone support for urgent Campus-IT issues via extension **1420**.

### Service Transparency
The URZ demonstrates a commitment to operational transparency by publishing annual [[ausfallstatistik]] (failure statistics) summaries. According to the newly generated version, these reports are available from 2013 to 2025 and track the reliability of the university's technical infrastructure.

## Location and Contact Information
The URZ is located on the Berthold-Beitz-Platz campus, adjacent to the [[universitatsbibliothek-ub]].
