When I look to the map, changes are not shown correctly. Some tiles are still old. But when I do an refresh (Ctrl+Shift+R) in Firefox, some new tiles becomes old and some old becomes new. And when I do refresh more times in the row, I even got all tiles old.
Initially I thought, that there is some issue with sync of tiles servers, but If I look to the some tile on all tile servers, after some reloads, all are old. My changes are not visible.

Tile is clean. Last rendered at Sat Jan 01 00:00:00 2000. Last accessed at Sun Jul 31 19:40:09 2016. Stored in file:///srv/tile.openstreetmap.org/tiles/default/17/16/26/174/53/0.meta
(Dates might not be accurate. Rendering time might be reset to an old date for tile expiry. Access times might not be updated on all file systems)
After some forced reloads I got: Mon Aug 01 11:02:37 2016. But later on, (on the same server) again Sat Jan 01 00:00:00 2000.
I never seen such behaviour. Previously, when tile was re-rendered, the new version was always served. But not now. And I don’t know, if this is normal or not.
I suspect this is to do with the proxies between you and the server. Whilst what you did should override proxies, you may find that one or more of the ISPs in line have very aggressive caching policies. This might be on transparent proxies.
