Help reverting changes

Can someone help revert all of the changes of user “margonotmango” to Cambridge, MA? One of changesets that has to be reverted is 44170250, but it’s not the only one. They all seem to be a mistake by a novice user, but JOSM is unable to revert them because “read times out” (perhaps the changesets are too large). Is there any way around it?

I’d suggest sending an email to the Data Working Group via about it. Someone there will be able to fix the problem.

Best Regards,

Thanks. Frederik (DWG) is now looking into it.
