Dear Atlas hosts, A while ago we introduced the option for hosts to write off their probes in case they were sure it was never going to be connected again. For instance if it was broken or lost in the mail, a software probe you only used for testing. etc. This written off status was recorded in the database and we show it on the current probe page but it was not reflected in the probe API or on the probe archive API. Starting today, this will change. There is now a new status ID: 4 in the probe API and after we create the probe archive for today, this will also be visible there. Sometime today we will update the status field on the previously written off probes. This will add roughly 5500 probes to this status and will lower the number of abandoned probes with the same amount. Please let us know if you notice any unexpected behaviour. We hope that this change will make the status of probes more clear to both hosts and users. Happy measuring! Johan ter Beest RIPE Atlas Team
