Official Rust servers, listed

Officially, it means a server run by Facepunch or by a partner network they have approved, not one run by an independent community owner. That is a question of who runs it, not what settings it uses. Check the tags column: most official servers are vanilla, but a few are marked modded.

Most leave team size at Rust's default of eight, which is why the group column is often blank. A minority do set a cap, usually three or four, and that changes a wipe if you play solo or as a duo. The cap appears in the group column when it is set.

They sit in the in-game Official tab, where most players look first, and the regulars know the wipe times. The busiest run several hundred slots and still queue when a wipe lands. Joining within minutes of the restart helps; so does picking a partner server with the same wipe day and a shorter line.

Facepunch's force wipe resets every map on the first Thursday of the month at 19:00 UK time. Individual partners set their own cycles on top of that, usually on the same weekday every week or two. The next-wipe estimate in the table follows observed behaviour, so use it over a published schedule.
