Latest published values

6 served · 0 withheld

Each row is what the operator’s latest published dataset reports for one combination of direction, technology, measure, firmness and horizon. Hosting-capacity figures are indicative and reflect what operators publish. They are not a connection offer; only the operator can confirm capacity for a specific request.
