AM.SE650 is in a remote location, and the cellular modem it uses has probably gone offline. Should be reset within 24 hours. Not a tech problem, just information in case SE650 is the most important Raspberry shake on Earth!
Thank you for the info paulgrace, and welcome back to our community!
I can see that the station is fully back online Station View: Raspberry Shake Network & EQ Activity Map so I’m glad to hear that the cell modem is continuing to work fine!
We all know the issues of putting a Shake out in the field.
