AppNexus Expands Real-time Bidding Globally With New Data Center in the Netherlands

Press Release

NEW YORK,  AppNexus, the real-time ad platform, today announced that it has opened its first data center outside North America -- in Amsterdam, the Netherlands -- a move which significantly expands the opportunity for real-time bidding (RTB) in Europe and the Middle East in response to rising demand among global ad networks, demand-side platforms (DSPs) and other online advertising companies in those regions.

AppNexus' state-of-the-art platform provides clients with unified access across all major RTB ad exchanges including Google's DoubleClick Ad Exchange and Microsoft's AdECN, as well as a cloud infrastructure scalable to tens of billions of ad impressions a day.  AppNexus has already established itself in the international market, working with customers such as BannerConnect in the Netherlands, mexad in Germany and Infectious Media in the United Kingdom.

"RTB has gained significant traction in the United States which has earned the attention of sophisticated online advertising companies around the world," said Brian O'Kelley, CEO of AppNexus. "Proximity to the ad servers of the major European publishers and ad inventory sources, however, is critical when the ads need to be served in real-time. With our new data center in Amsterdam, we're excited to bring more robust RTB capabilities to ad networks, DSPs and other clients in the European market.  Our partners are seeing incredible results in the US, and now this trend will be a global game-changer for online advertising."

According to proprietary AppNexus server data, daily real-time impression volume across Europe and the Middle East can reach billions per day.

"Collective has a strong partnership with AppNexus in the United States to deliver real-time bidding to our clients," said Jerome FitzGibbons, EVP, Collective.  "Now that Collective has entered the UK market, and AppNexus has opened their European data center, we can certainly see a good fit going forward to bring the benefits of RTB to companies in this critical market."

"Real-time bidding is an enormously exciting new chapter for display advertising, and will be another powerful tool for BannerConnect to deliver quality, high-performing advertising to our clients," said Sebastiaan Schepers, COO, BannerConnect. "AppNexus is a key technology partner of ours, and having its new data center in the Netherlands is a critical step in bringing RTB to our shores."

AppNexus' data center in Amsterdam, co-located in a world-class facility at the Equinix AM1 IBX, offers multiple currency and time zone capabilities, and 24-hour support with transit latencies well under 10 milliseconds to much of Europe.
