Host a DayZ Server in Canada
DayZ Manager last counted 50 ranked DayZ servers in Canada, with about 472 players on them. Canadian players split between Montreal routes into the US east and Vancouver routes into the US west. Pick the coast your roster already uses.
On the latest index, the busiest map tokens for Canada were Chernarus (27), Namalsk (5), Deer Isle (4).
Slot math is local. A 60-slot Chernarus box that is full on Friday does not need 120 slots on Tuesday, and an empty high slot count is how spoof complaints start. Size the machine for the peak you have already seen on the Canada roster, then add headroom for mods. City and mod-map missions cost more than a quiet vanilla coast.
The DayZ dedicated server is Steam app 223350 on the public branch and 1042420 on experimental. Players still use the DayZ client, app 221100. Ports are UDP, commonly 2302 through 2305, plus the Steam query port. BattlEye RCon is its own UDP port, usually the game port plus 3, set in BEServer_x64.cfg or beserver_x64.cfg. RestrictRCon must be 0 if you want kicks and bans to work.
CFTools Architect is the host for that process: install, mods, updates, restarts. CFTools Cloud is the game server management product on top, including BattlEye RCon, so you are not leaving a password in a desktop shortcut. Pricing for both lives on cftools.com. This page does not invent a monthly number.
If you only wanted to play, use the Canada server list instead of renting anything. If you are opening a community, write the map, the perspective, the wipe, and the language into the hostname before you buy the second month.
