Advertisers can select countries for their campaigns

We developed a new feature that enables advertisers to restrict their campaigns to certain countries. If the list of allowed countries is empty then all the countries are allowed (unless they are listed as disallowed).

However it doesn't yet affect how advertiser's moneys are being spent on ad units. It just replaces advertiser's ad with default ad if visitor's IP belongs to disallowed country.

Possible downtime due to server maintenance

Our hosting company is going to do some urgent maintenance work from 9:00 to 11:00 AM CET. Short downtime of our main site is expected. Ad rotation won't be affected.
