Changing isp increased the number of ads

For last week, only Air* was being used, because the monthly billing period was ending on 10 January 2016 and the data transfer would be lost. It was observed that almost no new ads were being requested on a advertiser website. Now the Id* expiry date is approaching, so the AIr* connection is not being used.
It has been observed that there is a significant increase in the number of ads being displayed with the different ISP connection. Are others also facing the same problem.
What could be the logic in the change in the number of ads
