Pertti Salmijarvi - ksvvnet Keski-Suomen Valokuituverkot Oy: downstream relationship
The downstream relationship between Pertti Salmijarvi and ksvvnet Keski-Suomen Valokuituverkot Oy appears in publicdata.caida.org (public_as_relationship_dataset) with a visible network relationship context. Public relationship documents link Pertti Salmijarvi and ksvvnet Keski-Suomen Valokuituverkot Oy through a downstream network relationship. The profile explains what is currently visible and what could change the assessment.
Why it matters
The downstream relationship between Pertti Salmijarvi and ksvvnet Keski-Suomen Valokuituverkot Oy matters because infrastructure decisions depend on knowing the organizations or individuals that appear in routing, registry, service, or governance mapping. The profile gives readers a bounded view of the identity, the visible operational role, and the facts that could alter the assessment.
What the sources show
The available documents establish the basic identity and operational context of the downstream relationship between Pertti Salmijarvi and ksvvnet Keski-Suomen Valokuituverkot Oy. Registry, routing, official, or operator-published documents can show visibility in the internet ecosystem; claims of ownership, customer status, or decision-making authority still require corroboration.
The downstream relationship between Pertti Salmijarvi and ksvvnet Keski-Suomen Valokuituverkot Oy appears in public evidence as a network relationship within the internet infrastructure ecosystem. No ASN or prefix sample is yet attached; current documents establish the identity, registry, or affiliation context. Contact coverage includes 0 operational channels that can help readers understand escalation paths.
The public record is useful when it shows presence in registries, routing or service footprint, operator-published channels, and official source documents. The article does not infer contracts from these signals. Its value is to identify the organization's visible operational surface and future events that would confirm or change relationship claims.
Operational surface
Public relationship documents link Pertti Salmijarvi and ksvvnet Keski-Suomen Valokuituverkot Oy through a downstream network relationship.
No ASN or prefix sample is yet attached; current documents establish the identity, registry, or affiliation context. Contact coverage includes 0 operational channels that can help readers understand escalation paths.
The impact mechanism is how changes in registry, routing, service, or relationship can alter assessments of accountability, accessibility, escalation, or dependency. The main subject is a company; network identifiers and registry records provide the main subject's context.
Watchpoints
Monitor changes in source freshness, footprint expansion or contraction, contact renewal, and disagreements between registry facts and operator-published documents. Add clearer corroboration before making stronger relationship or control claims.

BTW publicly records a stable downstream network relationship between Pertti Salmijarvi (AS51728) and ksvvnet Keski-Suomen Valokuituverkot Oy (AS43016) as evidenced by consistent CAIDA AS-relationships data from May and June 2026. ksvvnet functions as the upstream provider, while Pertti Salmijarvi operates as the customer, indicative of a transit purchase arrangement.
Watchpoints
- Changes in ASN ownership or registration details for either party
- Appearance or disappearance of the AS pair in public routing data (e.g., CAIDA, RIPE RIS, RouteViews)
- Shifts in relationship type (e.g., from downstream to peering or sibling) that would alter dependency models
- Service footprint expansions or mergers affecting either entity
Caveats
- The relationship classification relies exclusively on CAIDA's inferred AS-relationship model; no bilateral contracts or direct confirmations are available.
- Downstream directionality is interpreted from standard commercial conventions but has not been independently verified with operator statements.
- The profile represents a snapshot; relationships can change without immediate public reflection in routing datasets.
