What happens if Yundera's servers go down?

Your apps and data are safe. They live on your PCS, not on Yundera's servers.

What continues to work​

  • All apps keep running on your PCS
  • Local network access (same Wi-Fi/LAN) works normally
  • Data remains intact and accessible

What would be temporarily affected​

  • nsl.sh domains — external access via appname-you.nsl.sh would be unavailable
  • WireGuard tunnel — if your PCS is behind CGNAT, external access through the tunnel would stop

What still works for external access​

  • sslip.io addresses — if your PCS has a public IP, appname-x-x-x-x.sslip.io still works (no dependency on Yundera)
  • Custom domains with direct A record — bypasses Yundera entirely

Key takeaway​

Yundera is a convenience layer for reachability. Your data and apps are always yours, always local.
