1 - DAIC downtime and migration plan update

Maintenance reminder and updated timeline for DAIC migration to the new environment.

The migration to the new DAIC environment is progressing. Based on the latest planning, we have updated the migration timeline previously announced in July 2026.

Updated migration timeline

  • Now - 2 October: both the current and new DAIC environments are available.
  • 3 - 11 October: both environments will be unavailable due to planned data-centre maintenance.
  • From 12 October: both environments will return to service, with accounting enabled on the new DAIC environment.

Migration to the new DAIC

Users of the current DAIC can already request access to the new environment via TopDesk (Please select the DAIC-other as Contact/ Contributing group), and we encourage you to start migrating and testing your workflows where possible.

The hardware itself will migrate in stages:

  • Mid-October: approximately half of the remaining hardware in the current DAIC will move to the new environment.
  • Early November: the remaining hardware is planned to move to the new environment.

Newly acquired DAIC hardware will be installed directly in the new environment.

Documentation for both environments remains available during the transition:

Current DAIC: https://daic.tudelft.nl/ New DAIC: https://doc.daic.tudelft.nl/

Planned maintenance: 3-11 October

Both DAIC environments will be unavailable during the maintenance period. The maintenance may also affect other ICT services, including parts of the central storage infrastructure and virtual servers.

For more information, please see the TU Delft ICT announcement.

We will communicate further updates as the migration progresses.

2 - DAIC Fall 2026 hardware expansion round

DAIC Fall 2026 hardware expansion round – call for research group participation.

DAIC is opening its Fall 2026 hardware expansion round.
Research groups interested in contributing compute resources are invited to participate.

Given current market signals indicating expected price increases (particularly for memory components) it is important to consolidate commitments early to secure favorable pricing.

Contributions will expand the shared GPU capacity available to participating groups.

Participation Window

Expressions of interest are requested by mid-October 2026.
Final commitments will be coordinated directly with participating groups.

Deadlines will be enforced to ensure timely procurement.

How to Participate

Groups interested in participating are encouraged to contact the REIT team to discuss:

  • Intended contribution amount
  • Funding source and project code
  • Hardware preferences

3 - Start of DAIC migration to new environment

4 - DAIC maintenance: 3-11 October 2026

Scheduled DAIC downtime due to TU Delft data centre maintenance.

DAIC will be unavailable from 3-11 October 2026 due to planned maintenance in TU Delft’s data centres. This applies to both the current and the new DAIC environment: neither can be used during the maintenance window.

Please plan your work accordingly. Jobs running before the maintenance may be interrupted, and new jobs should not be scheduled during this period.

The maintenance may also affect other ICT services, including parts of the central storage infrastructure and virtual servers. The exact impact on individual services will be communicated by ICT where applicable.

For more information about the maintenance, please see the TU Delft ICT announcement.

After the maintenance window, from 12 October 2026, only the new DAIC environment returns to service. See the migration announcement for the timeline.
