Nether hub

Take your base Overworld X and Z and divide by 8 to get the target Nether coordinates. Build your Nether-side portal near that point, then place your Overworld portal at the base where you want it. If other portals are close, move one end and re-test until the pair is stable. Small shifts can change which portal gets chosen, so avoid building right next to someone elses portal bay.

A fully enclosed corridor with a roof, solid lighting, and spawn-proof flooring (slabs, buttons, or other non-spawnable blocks). Add railings over lava, block line-of-sight for ghasts in exposed areas, and put portals inside small rooms so players do not step out into the main lane. Signs with destinations and coordinates prevent wrong turns and accidental trips.

Dense portal clusters are where mislinks, crowding, and performance problems start. Spacing rules keep routing predictable and reduce the chance that players load multiple portals at once. Most servers keep the center for junctions and community portals, then push personal portals down branches or into assigned bays.

Ice roads usually win because boats on packed ice or blue ice are fast and cheap to run once the build is done. Rails are slower and resource-heavy but feel simple and reliable early game. Many hubs begin as walkable tunnels, then upgrade the main trunk to ice when the server can afford it.

It can be, because everyone funnels through shared corridors and portals. Servers that keep it healthy treat the hub as protected commons: no traps, no lava dumps, clear rules for public routes, and logs or rollback for vandalism. Good norms do as much work as good blocks.
