FragNode Rust Wipe Server RAM & DDoS VDS Blueprint
Facepunch procedural maps generate 150,000 to 300,000+ Unity physics colliders at boot, meaning a 4250 worldsize wipe server with Carbon or uMod/Oxide plugins demands isolated 32 GB to 64 GB DDR5 memory, high single-core clock speeds, and inline RakNet UDP scrubbing.
FragNode wipe rule: set +gc.buffer 4096 on 32 GB+ VDS nodes to suppress Unity GC rubberbanding.

Because public wipe days combine heavy entity collider loops with frequent UDP volumetric floods, FragNode maps 60-to-150 population Rust servers to UltaHost 32 GB or 64 GB Dedicated VDS plans ($37.50/mo to $68.00/mo retrieved 2026-11-12) or bare-metal Ryzen 64 GB servers on InterServer ($89.00/mo in US regions). Private 10-to-25 player build/PvE servers fit Hostinger Game Panel 8 (32 GB NVMe at $21.99/mo).

-
FragNode Engineering Check #1
Raising +gc.buffer from the default 256 MB to 2048 or 4096 MB prevents Unity garbage collection from freezing all players every 4 minutes once base entity counts pass 180,000.
-
FragNode Engineering Check #2
Cap +fps.limit at 60 rather than leaving server FPS uncapped at 250+, cutting CPU thermal throttling and power draw while keeping projectile validation crisp.
-
FragNode Engineering Check #3
Never leave WebRCON TCP 28016 open to 0.0.0.0; bind RCON to localhost or strict WireGuard admin IPs while keeping TCP 28082 open for the Rust+ mobile app.

FragNode Engineering FAQ: FragNode Rust Wipe Server RAM & DDoS VDS Blueprint
How does map worldsize impact RAM in the FragNode Rust blueprint?
A 3500 map typically consumes ~9 GB to 11 GB at startup before players join, whereas a 4500 map with monuments and Carbon plugins routinely exceeds 18 GB to 24 GB.
Why does FragNode differentiate Carbon and Oxide plugin counts?
Each active raidable-base, clan-ui, or loot-table plugin allocates managed C# memory hooks per entity spawn, which FragNode models in Zone 3.
Which port must stay open for the official Rust+ companion app?
Open TCP port 28082 (or server.port + 67 by Facepunch convention) and pass +app.port 28082 in your startup script.
