[OSM-talk] Bandwidth limit/IP blocking - Error 303 on the OSM API?

[Jaak Laineste]

Hi,

 this reminded me an issue what I've had twice - I had made two
sessions of hands-on trainings for OSM, with about 30-40 computers in
a classroom. In both cases when they started to do actual data
download/editing, then last ones were rejected from API calls. Perhaps
just as we were under same IP address. You can imagine that having
this technical issue in front of the all the leading geography
teachers of our country can be quite embarrassing.

 Is there a procedure or contact to register an IP for temporary
higher load for such cases?
