Question 1

How reliable is Kärkkäinen Oy?

Accepted Answer

Kärkkäinen Oy's reliability is measured by the independent Symbioen Index — a score built on verified charging performance, not on operator-reported uptime, which consistently overstates real-world reliability.

Question 2

What is Kärkkäinen Oy's availability?

Accepted Answer

Symbioen measures availability independently from AFIR data feeds — the share of time a charger is operational and reachable — rather than relying on operator-reported uptime, which diverges sharply from real-world charging success.

Question 3

How is Kärkkäinen Oy's charging reliability measured?

Accepted Answer

Symbioen measures Kärkkäinen Oy's reliability from AFIR-mandated National Access Point data — government feeds that operators are legally required to publish — not from operator self-reporting. The same methodology applies to every operator, so scores are directly comparable across the market.
