There is a whole ecosystem of servers providing OSM data http://wiki.openstreetmap.org/wiki/Planet.osm There are a couple of sources for excerpts or diff files listed on this page. http://wiki.openstreetmap.org/wiki/ROMA http://wiki.openstreetmap.org/wiki/TRAPI These two services are optimised for queries to make a map of the data. They are intended to be only some minutes behind the main server but don't offer all the tags. So you should not use the data for further editing. http://wiki.openstreetmap.org/wiki/XAPI This is the well known alternative to the main API. It's also intended to be only minutes behind the main server. It has an extended API with still a concise syntax. The data is usable for editing. The only tag that is filtered out is "created_by" - this tag can safely be ignored. http://wiki.openstreetmap.org/wiki/OSM_Server_Side_Script This one is very recent and still in a state of playground. It is intended to serve particular complex queries beyond the scope of XAPI. It also offers (almost) the complete functionality of XAPI. It is some hours behind the main API. It does not serve data that can be used for editing, in particular it does not provide version information. If somebody asks for version number support (or other metadata), I'll start to implement that. There has been no demand so far. There may be other storage servers, the category "Data storage" on the wiki is not yet written. But at least, there are plenty of alternatives to download data from the main server.
