Might want to query your provider as to where the rate limitting is being done. In some cases, if rate limit is being done egress from the layer 3 infracture towards the MAN layer 2 equipment, there might be a lack of processing power on that device, causing the drops. Of course this will depend on the type of device and whether the rate limiting is being done on hardware or not too.
