We are sorry that IPv4 of Freeshell nodes 1 & 7 is broken since the maintenance yesterday. It is because we did not write network routing configurations into persistent storage, and the configs were in an inconsistent state after reboot. This problem is fixed now.

If you have any problem regarding network connectivity, please let me know.

Thanks wl56 for bug report.
