Why is the openstreetmap.org website really slow to upload changes ?

When I click on the Save button to upload my changes to the openstreetmap.org website, it takes forever to save to the changeset.

Is openstreetmap.org having website problems ?

Waiting for minutes to upload your changes inside the Potlatch2 editor is **not **normal.

If there are some severe troubles with any server, you should find a hint at http://wiki.openstreetmap.org/wiki/Platform_Status
