Hi,

you are most likely hitting the limits that have been announced since last year in our robot policy, and very clearly stated there, which we started enforcing progressively and finally got applied fully in January.

What's most likely happening is that you haven't set proper contact information for you InstantCommons User-Agent, see https://www.mediawiki.org/wiki/InstantCommons#User-Agent_Policy

Cheers,

Giuseppe

FYI, this new limit seems to be affecting the InstantCommons feature used by many (if not most) external wikis. At appropedia.org we're experiencing many broken images, apparently because we've reached our request limit. This can actually be a good thing because it has forced me to upload to our server some images that were being used many times via templates and that shouldn't have been loaded from Commons in the first place. I just wanted to bring this up because it isn't currently documented at Wikimedia APIs/Rate limits.

That seems very easy to hit just doing some searches from the search
bar. How are we going to detect the collateral damage on unregistered users?
