The normal process, is that on a regular basis, the map tiles update process runs on the servers. When it starts, any edits which are complete by that time will be included in the current map update cycle. The [[map tile]] updating process can take several days or even weeks on the World server, and are currently happening approximately daily on the North American server. Depending on when you save the edit, on the North America server, it will appear in 1 or 2 days. More details are covered in the [[Timeline of updating process]].
