Where did all the online ads go?
Google’s DoubleClick for Publishers ad server went down for nearly two hours on Tuesday, shortly after 9 a.m Eastern. Service began to return around 10:45 a.m., restoring revenue-generating advertising to millions of websites.
Online monitoring company DynaTrace told Campaign 315 global DoubleClick outages affected 55,185 websites.
To make matters worse, the shutdown caused some websites, such as Forbes.com, to freeze because interstitial ads are failing to load.
While it had already acknowledged the problem to publishers in its private DFP Google+ Google officially confirmed the outage at 11:30 a.m.:
"DoubleClick for Publishers experienced an outage this morning impacting publishers globally, across their video, display, native and mobile formats. Our team has worked quickly to fix the software bug and DFP is now back up and running, so our publisher partners can return to funding their content."
This is not the first time Google has had trouble with DoubleClick recently. In September, DoubleClick ad servers exposed millions of users to malware.
The last time DoubleClick shutdown was March 2013, eliminating ads across the web for several hours.
