Since yesterday on the www.openstreetmap.org website (visited with IE 9 and Firefox11), the tiles provided by the server tile.openstreetmap.org (mapnik, mapquest) are not more shown using my local ISP. After a while of waiting, the left part of the website appears as usual with the OSM symbol, search bar etc, whereas the central map part remains blank, and the message "waiting for c.tile.openstreetmap.org" permanently appears in the status bar of the web browsers. When choosing the public transport map whithin the map options of the osm website (tiles provided by opencyclemap.org), then the public transport map is shown without any problems.

I made a tracert attempt to see if both tile servers can be contacted from my IP on, it worked fine in both cases (see attached tracert protocols).

My local ISP here in the brazilian town where I am mapping is attributing the IP 189.43.38.34 to all of its clients. Is it possible that this collective IP has been blocked by the OSM admins to prevent receiving map tiles created by the tile.openstreetmap.org server?

When I used another IP by a VPN network from the same computer on (connected physically the same way to my local ISP) to access the www.openstreetmap.org website, then all tile.openstreetmap.org tiles were displayed. Thats why Im thinking that something has been blocked.

Sincerely,
