I have just found out that there is a new rate limit change in the Ads API, that will become effective today (2011-11-11).

As stated, the rate limit will be affected by the level of access a particular application has.
We have started using the Ads API about a year ago, when there were no access levels, so I don’t know how to get my current access level. I would like to understand how our app is affected by this rate limit change
