It doesn't help, when we're talking about Atlas probes. I have one probe, where external flash died twice, even it's placed in datacenter with UPS-protected power. On 23.05.16 15:35, "ripe-atlas on behalf of James R Cutler"

+1. I lost most of the probes this way and I'm not really sure how to recover them - I need to ask for a batch of USB drives or ask all the hosts to remove them... can't this be handled better with a firmware replacement? I would at least then ask all the hosts to unplug the USB and leave the
