去年“黑五”前夕，Facebook旗下Ads Manager服务器出现故障，很多广告主在“黑五”购物季高峰期间无法使用平台的广告投放功能，也无法将广告创意上传或下载报告。虽然Facebook发言人在事后表示平台故障问题已经得到解决，但经历这次事件后，很多广告主反应Facebook平台的广告效果在不断变差，Ads Manager从最初的无法发布广告、关闭投放演变为投放效果出现了严重的不连贯性。

On the eve of last year's "black five", Facebook's ads manager server failed. Many advertisers were unable to use the platform's advertising function during the peak of the "black five" shopping season, and they were unable to upload or download advertising ideas. Although a Facebook spokesman said afterwards that the problem of platform failure had been solved, after the incident, many advertisers reported that the advertising effect of the Facebook platform was getting worse and worse. Ads manager changed from being unable to publish ads and closing the launch to being seriously incoherent.

ROAS Media美国业务负责人约翰·博林(John Bolling)表示，“自去年Adsmall遭遇4个多小时的失败以来，Facebook平台的广告表现每天都在波动，2019年初Adsmall的问题越来越严重。”
