API...
"HTTP Error 403 - Forbidden" connection have been blocked. This is
used on mass downloaders who degrade the API for mappers. [*]
"HTTP Error 509 - Bandwidth Limit Exceeded" requested excessive
amounts of data in a short period. Automatically removed after dropped
below threshold.
API + WWW served an average of 2529965 requests per day for May 2011.
Tiles downloads are auto-magically slowed down after reaching a high
threshold. Number of IP addresses currently being slowed down:

Tile downloads are normally in excess of 1000 per second.

Yes. The replication diffs contain all the changes applied for the period.
*: There is also an ancient release of JOSM blocked which flips
lat/lon coordinates.
