Hello,
After internet connection is down zerotier-cli status does not change status to offline for 8 minutes and 30 seconds which is quite misleading for a significant amount of time. Digging deeper I found out that interval can be changed in node/Constants.hpp by changing value of #define ZT_PEER_ACTIVITY_TIMEOUT. Would changing this value affect the connection itself in any way? I am thinking of changing it to 60000 (one minute) to narrow the window and it works as expected, status changes after a minute.
