Notifications Notify me at my registration address if this probe is down for more

Hi, On the portal: than 600 minutes. This doesn't seem to take into account that a probe may be dual-stacked (v4 and v6) and just one of these protocols may fail w/o the other one failing as well (this is a problem with my CPE, but I'm not touching that box until the temperature in the lab has dropped to sensible values) In any case, if v6 dies but v4 still works, the probe doesn't complain. Perhaps this should be flagged separately? How are we doing on testing silent v6-failures in general? Happy eyeballs make a lot of breakage invisible.. Geert Jan
