As the OSM servers are up and running since Tuesday, I did some live mapping using the famous osm2go yesterday. Unfortunately it has problems uploading the edited data. The error it emits reads as:
Uploading to http://api.openstreetmap.org/api/0.6
Create changeset failed, code: 417 (Expect rejected)
Others also had similar problems, so it should be possible to locate the issue during the next couple of days.
