First paragraph: "we are forced to increase the prices of many of our products by approximately 10%"

Missed that. Thanks!

The article gives the prices in a table in you scroll down a bit :

electricity/air conditioning rate old price* new price*\

Germany € 0.29/kWh € 0.45/kWh

Finland € 0.12/kWh € 0.22/kWh

That's the price for electricity/air conditioning (presumably for Hetzner), not how much their products will rise in price.

It is the electricity/air rate for their colocation service
