Hi I've been getting an error recently using OSM History Browser on a few entities:

xmlhttp.responseXML is null

Example: Relation 3126449 If I try preceding relations (3126448 etc) it works.

I thought there maybe something wrong with the way it's stored in OSM but other validators & indeed, OSM the main page displays it correctly graphically.

Are you getting the same results?

Are there any other history checkers which could be used?

Other standalone "large object viewer" options:


works on nodes and ways, but not relations, and shows tags, values and (for ways) component nodes.

For relations:


Works for nodes, ways and relations; shows tags and values only.

This tends to happen with any large relation.

I guess the most reliable viewer is JOSM, probably using File->Download Object to fetch the data.

(for completeness) JOSM "download object" is only doing the same as https://www.openstreetmap.org/relation/3126449 , not https://www.openstreetmap.org/relation/3126449/history . From there you can "view history" but it doesn't actually show you the history, only who has edited it. You then have to manually hunt out versions like you would with changes to a wiki page; you can't just search like you would be able to if https://www.openstreetmap.org/relation/3126449/history didn't time out.
