does this affect AS3209 or AS3320? In the past it was very helpful to have many probes in their (large) access networks to track down a strange issue in AS3209 (different probes in the same IP prefix (as seen in BGP) showed a different behaviour).
Software probes that connect from networks beyond these limits will not be allowed to connect, unless and until other software probes drop out. Note that we may also adjust the particular maximums over time.
Will there be a clear reason in the web interface for probe hosts? Just seeing a probe as "Disconnected" (and maybe even receiving an e-mail that my probe was/is disconnected) would not be helpful from my point of view.
While in the past we observed surprising corner cases, the particular limits described above are set partially taking into account the current software deployment. Therefore only a handful of probe hosts should be impacted by this (as I write this, 71 probes from 13 hosts). As I mentioned above, we’re open to adjust the limits if needed.
How would I figure out whether I am one of the mentioned 13 probe hosts? Regards, Robert
