[atlas] 4 probes on different networks suddenly down?

Hi, At noon today 4 of my probes disconnected. 1005229 61071 55795 1005072 These are on different ISP’s and one of these is in Oracle’s cloud. So this is not a problem on my side. Restarted the 61071 since that one is nearby and easily restarted since it is a hardware probe, but that does not work. Flashing red LED. What is going on? Regards, Ernst J. Oud
