What is automatic failover and why it matters for online games

Failover is the automatic switch from a connection that failed to a backup one. In online games, that means: if your internet drops, game traffic switches to the second line before the server even notices.

Manual vs automatic failover

Manual (what most people do)

  1. Internet drops
  2. You notice it dropped (can take a few seconds)
  3. You unplug the cable, plug another one in, or switch Wi-Fi networks
  4. You wait for the new connection to stabilize
  5. You reopen the game and log in again

Total time: 30 seconds to several minutes. In that window, your character is already dead in-game.

Automatic (with PingArmor)

  1. Internet drops
  2. PingArmor detects it in ~1.5 seconds
  3. Traffic is switched to the second internet automatically
  4. The game keeps running normally

Total time: ~2 seconds. The game server never notices the switch.

How PingArmor detects problems

Monitoring runs in real time, with two detection layers:

Drop detection (gateway ping)

PingArmor sends a ping to the gateway of your primary interface every 750 milliseconds. If it gets no response 3 times in a row (~2.25 seconds), failover kicks in.

Lag detection (game server ping)

Full drops aren’t the only problem. Sometimes the internet is “working” but the route to the game server is congested — the classic route lag.

PingArmor tracks real latency to the game servers. If ping goes above the configured threshold (default: 150ms), it switches to the second internet. That can force a new route and clear the lag.

In practice: each automatic switch counts as a "save" on the dashboard. Those are drops or lag spikes you never felt in-game.

The WireGuard tunnel

PingArmor doesn’t just do failover — it builds an encrypted tunnel between your PC and a relay server using the WireGuard protocol.

Why that matters:

  • Fixed server-side IP — when you switch internets, the IP that changes is the one on your PC, not the one the game server sees. That’s why the switch is transparent.
  • Encryption — all traffic is encrypted, protecting against interception.
  • Instant reconnect — WireGuard is stateless, so there’s no slow handshake when reconnecting.

How long does the switch take?

ScenarioDetection timeTotal time
Full internet drop~2.25s (3 failed pings)~2.5s
Route lag (high latency)~1.5s (2 readings above threshold)~2s
Failback (back to primary)15s of stability + switch~16s

Failback is intentionally slower — PingArmor waits for the primary to stabilize before switching back, to avoid flapping.

In practice: supported games

PingArmor auto-detects connections to RubinOT and Tibia Global. Once the tunnel is up and you open the game, routes are configured automatically — zero manual setup.
