About this network

ASPECTRA (AS9100) is the network of CONVOTIS Swiss Cloud AG, the Zurich managed-hosting provider founded as aspectra AG and acquired by the CONVOTIS group in 2024.

What it's used for

The AS carries dedicated and managed hosting: physical and virtual servers, private/hybrid cloud and application management run out of Swiss high-security data centres. Its inventory is a set of two dozen scattered /24s and small blocks (roughly 5.9k addresses) with ~43 observed neighbours, the shape of a mid-size managed-services host rather than an eyeball or transit network. The customer base skews to regulated sectors (financial services, healthcare, public administration, online retail), and the company holds ISO 27001 and PCI-DSS certifications.

Notable

• Registered since 2001; aspectra rebranded under CONVOTIS Swiss Cloud AG after the 2024 acquisition, so the ASPECTRA handle now outlives the original company name.
• No PTRs were returned on the addresses sampled.

Interesting

CONVOTIS positions the combined entity among the top managed-IT service providers in Switzerland.
