Access to Dublin Gateway

Hi

Is the Dublin gateway still up and could my nodes get access to it? If so, is there any information or sample configurations/sketches available that highlight required configurations that is needed.

Initially I would like to try connecting, via LORWAN a simple temperature sensor Arduino node with a temperature sensor with either a RFM95 or RN2483 radio, to the gateway and have the readings sent to either thingspeak or Xively.

I have managed to do this via a simple LORA gateway based on a python script running I wrote on a Raspberry pi but would like to update my nodes to use a public Lorawan network instead. Any help doing this would be appreciated
