The whole site is down and I can’t upload any changesets. It doesn’t appear maintenance related.
You can see some stats here:

Hopefully this is not another purposeful attack on OSM.
Edit: Site is up now, but the database is read-only. See: https://en.osm.town/@osm_tech/113656639378201391
Edit 2: Everything may be operational as of Tuesday evening (Europe)
Edit 3: Everything’s back.
OSM…And… Cache?
