Boss events on a large world, with 15 players and no slowdown.
Terraria boss events fill the screen with projectiles, and a large world gives the server more tiles to track. Every player, minion, and projectile is simulated each tick. Yours is online in under 3 minutes, with no player cap, tModLoader mods, and serverconfig.txt in your hands. Upload your own world, or let the server generate a large one.

Size it for your party
Player counts are where each size stays smooth, not a cap. Big content mods like Calamity push memory, so pick 6 GB for a modded large world.

tModLoader mods
Drop .tmod files into Mods, list them in enabledmods.json, and Calamity, Thorium, or Spirit are on.
serverconfig.txt, yours
World, seed, size, difficulty, max players, password, and message of the day, in one text file.
Live console and SFTP
playing, say, kick, ban, and save from the console, .wld uploads by browser or SFTP, sub-user logins for co-admins.
Backups you can restore
Schedule nightly backups in the Game Panel and restore the world from before the Wall of Flesh went wrong.
Boss events that hold
Terraria runs its world on one thread, so your server gets a 4.5 GHz single-core clock, benchmark published.
No noisy neighbors
Your node stops taking servers at 60% load; the cap and the policy are published on Receipts. Boss events get the headroom.
Engineers who answer
Tickets go to the people who run the nodes, not to a script.
Why the hardware matters for Terraria
Terraria runs its world on one thread. Every player, minion, enemy, and projectile in a boss event is updated by that core each tick. Your server runs on AMD EPYC 4565P at a 4.5 GHz single-core clock. The node stops taking servers at 60% load, so somebody else's game night cannot slow your boss fight. Both numbers are published on Receipts, with the benchmark run behind them.
Memory follows the world and the mod list. A vanilla medium world runs on 3 GB. A large world with a party wants 4 GB; add Calamity or Thorium and it wants 6 GB. World files sit on NVMe storage, so autosaves are quick. Watch the graphs in the Game Panel and step up a size when the mod list grows.

Your rules, your files
One text file runs the server. serverconfig.txt sets the world file, size, seed, difficulty, max players up to 255, port, password, and motd. Stop the server, edit it in the file manager, restart; the common values are also on the Startup tab.
Worlds are single .wld files in the Worlds folder. Upload yours by browser or SFTP and point world= at it, or change worldname for a fresh one. tModLoader mods are .tmod files in Mods, with enabledmods.json listing the active set; every player needs the same list. Schedule nightly backups, and type save in the live console before a restart.

About running Terraria here.
Explore the knowledge base or open a ticket in the Console. An engineer answers.
Is "4 players" a cap?
No. It is the party size the Desert server stays smooth at. Terraria itself allows up to 255 through maxplayers in serverconfig.txt. Invite more, and upgrade a size if a large modded world starts to feel it.
Can I run tModLoader mods like Calamity?
Yes. On a tModLoader server, .tmod files go in Mods and enabledmods.json lists the active ones. Every player needs the same set; recent builds prompt them to fetch missing mods from the Workshop.
How fast is it online?
Under 3 minutes from checkout. Your welcome email carries the server address and your login, and the Game Panel is ready when it lands.
Can I change the world, difficulty, or player limit later?
Yes. Stop the server, edit serverconfig.txt in the file manager, and restart. Point world= at an uploaded .wld file, or change worldname and autocreate for a fresh one. The common values are also on the Startup tab.
Can I upgrade later without losing the world?
Yes, from the Console. Pick the larger size, pay the prorated difference for the rest of the cycle, and restart to apply it. Your world, mods, and settings come with you.
Where does it run, and what if I want out?
Seattle, on racks we own, built for Pacific Northwest latency; the route is published on the datacenter page. No contract, and new servers carry the 30-day money-back guarantee. After 30 days, refunds are prorated at our discretion; request one within 72 hours of the charge.
