About this network
DIAG-AS is diag Dienstleistungen AG, a Swiss ICT services company founded in 1981 and based in Lachen, canton Schwyz. It runs its own datacentre capacity and sells hosting and managed IT to Swiss businesses.
What it's used for
- Hosting and private cloud, Microsoft 365 and managed ICT for regional business customers, served from the company's own facilities.
- A small footprint of 512 addresses across two /24s, sized for an integrator's hosting arm rather than a volume host.
Notable
- This is a hosting and managed-services network. Only a small number of addresses front public websites; most of the space supports customer workloads and internal infrastructure.
- Diag is ISO 27001 certified and leans on Swiss data-residency as a selling point, which is the standard positioning for a small Swiss host competing against the hyperscalers.
Interesting
- The company predates the commercial internet by more than a decade, having started as an IT services firm in 1981 and grown into hosting from there. Plenty of small European hosts have that shape: an integrator that eventually bought racks.
