A power outage affects both the server at your home and the travel router.

When the power goes out

The server loses power, terminating the VPN tunnel.

Internet access through the travel router is cut due to the Internet kill switch.

When the power comes back

The server router restarts automatically.

The VPN tunnel is re-established if there are no lingering issues with your home ISP.

Configuration

No data is lost or corrupted during the power outage.

The system is designed to handle power failures gracefully.
