[openstreetmap/openstreetmap-website] paginated browsing has disappeared from user changeset list (#1323)

Unfortunately they don't "work" for the poor server that in order to find page 7000 has to search through the preceding 6999*pagesize changesets.

Basically traditional paging is not sustainable on large datasets because each page is slower and slower to access as it has to read through the data for all the previous pages first and the simple fact is that no real person is actually going to browse through 7000 pages!

Presumably what you are really doing is binary searching by manually editing the URL to find the page which covers a particular date range you are interested in. Which puts you in the 0.001% of users that would have any idea how to do that.

The real solution, if I am right about what you are doing, is to add better methods to search for changesets by a given user in a given date range (which the server can do efficiently) not to bring back paging.
