Germany’s AI infrastructure

Germany’s AI infrastructure, where public data makes it measurable

We connect public EuroHPC facts with official infrastructure aggregates from Germany’s Federal Network Agency. Explore compute systems, AI factories and regional network assets—source-bound, without estimated capacity or a synthetic score.

Compare regional network infrastructure

Compare absolute source values only within the same administrative level. Larger and more populous regions will often have larger totals; this is not a quality or capacity ranking.

Federal, state and district rows are separate aggregates. Never add them across levels—that would count the same infrastructure more than once. A missing value means “not reported by the source”, not zero infrastructure.

The value compounds over time

The change history starts now

Since 13 July 2026, we have archived new source states in an auditable form. Once a second materially changed source period exists, we can show genuine changes by source period—unchanged weekly checks will not become a synthetic trend.

Methodology & limits

What the data proves—and what it does not

The private collection preserves auditable source states. The public site receives only a strictly bounded field-level projection with exact units and provenance.

  1. 1
    Check automatically

    A rule-based collector checks the approved EuroHPC and Gigabit sources weekly. Changed source states are archived immutably.

  2. 2
    Bound the fields

    Only published facts on a fixed allowlist enter the board. Raw files, run metadata, contacts and internal storage paths remain private.

  3. 3
    Keep levels separate

    Federal, state and district aggregates stay separate. Missing values remain missing; kilometres and item counts are never blended.

  4. 4
    Do not invent availability

    The data proves neither bandwidth nor free compute capacity, private GPU holdings, data-centre sites or grid headroom.

Absolute totals are not a fair efficiency comparison without area, population or network length. We therefore deliberately publish no infrastructure or AI-readiness score, and no map without separately audited boundaries.

Primary sources & licences

Every published value remains traceable to its source

The board is produced during the website build from the private archive. Raw and normalised archive objects have no public access path.

Frequently asked questions

What does the AI Infrastructure Index measure?
It connects public EuroHPC facts about compute systems and AI factories with official, regionally aggregated network-infrastructure data from Germany’s Federal Network Agency. It does not measure private compute or actual network and compute utilisation.
Are the area rows data centres or exact infrastructure locations?
No. The 417 rows are aggregates for federal, state and district levels and contain no facility coordinates. EuroHPC locations also remain at the precision published by the source: city or campus label.
Do fibre kilometres or PoPs prove available bandwidth?
No. They describe published infrastructure elements and routes. They do not establish available bandwidth, service quality or short-term spare capacity.
Why is there no AI-readiness score?
A score would mix kilometres, item counts, private compute, electricity, demand and regional size using subjective weights. The current evidence cannot support that, so the source values remain separate.
Why is there no map yet?
The source provides area codes and names but no geometry. A defensible map needs separately audited and licensed boundaries; raw totals by area could also be mistaken for density or quality.
Why are some regional values missing?
The source does not report every field for every area row. A missing value therefore remains explicitly missing and is never treated as zero.
Is HammerHAI already operational?
We retain the published planning status: system delivery in Q2 2026 and expected operation in H2 2026. The collector never turns an expectation into evidence of operation automatically.
Can JUPITER and HammerHAI performance be compared?
No. JUPITER’s HPC figures and HammerHAI’s peak AI-inference metric describe different workloads and units. The board never places them in one performance ranking.
How current is the data?
The approved sources are checked automatically each week. The board keeps the check date separate from the network source’s data period. Only material source changes create a new historical source state.

Plan infrastructure for your AI workload?

We translate workload, privacy, latency and cost into a robust cloud, EU or on-prem architecture—without pretending catalogue signals are availability commitments.
