It pretty much means exactly what it says - there are per-IP
restrictions on the rate at which data can be fetched with the map call.
They don't currently apply to Potlatch 1 which uses a different interface.

Nothing has changed in the limits we apply - they have been the same
since they were introduced several months ago.

You don't seem to be being throttled at the moment, though some of your
requests do seem to have been rejected earlier in the day.
