Summary
3-S-IT Dienstleistungen GmbH
enterprise hosting legacy
DREI-S-AS — 3-S-IT Dienstleistungen GmbH, a Vienna-based IT services
company that acts as the central IT provider for the Austrian Trade Union
Federation (ÖGB) and its member unions.
What it's used for
- Data centre operations, software development, and application hosting for the ÖGB and the individual trade unions.
- Connecting roughly a hundred union offices and sites across Austria.
Notable
- This is a captive IT shop, not a commercial hosting provider: the address space serves one organisational family rather than the open market. Traffic from it is union staff and union-run applications, so it behaves like enterprise space even though there is a data centre behind it.
- Handles member administration systems, which is exactly the kind of workload an organisation prefers to keep on infrastructure it controls end to end.
Interesting
- The
DREI-Sin the handle is simply the German for "3-S" spelled out — RIPE AS names cannot start with a digit, so the company wrote the number as a word.
