Yandex Ads restored some services after data center attacks
Yandex Ads has restored the operation of YAN, Adfox, and agency interface dashboards after data center attacks in October. Direct and Business remain limited, but running campaigns are working.

Yandex Ads has partially restored the operation of key services following October attacks on three of the company's data centers in the Ryazan region, Kaluga, and Vladimir. Clients again have access to the partner dashboard of the Yandex Advertising Network, the main functions of Adfox — a site monetization tool — and the advertising agencies dashboard. Full functionality of these interfaces is still being restored. "We continue to restore the full functionality of these dashboards," Yandex Ads reported.
What is still not working?
Access to Direct and Business personal dashboards remains limited. Managing campaigns, changing settings, and viewing reports is not possible. Previously launched campaigns continue to operate normally.
"The system accounts for actual impressions, clicks, and conversions, and collects and saves statistics on campaign results. The daily and weekly budgets you have set in your campaigns are being respected," the company said.
In simpler terms: advertisers' funds are being spent according to the set limits, and performance data is not being lost.
Why did the outage happen?
In October, the Armed Forces of Ukraine attacked three Yandex data centers — in the Ryazan region, Kaluga, and Vladimir. The damage led to widespread failures in advertising services: Yandex Direct, Yandex Metrica, Yandex Business, Yandex Advertising Network, AppMetrica, and others.
The consequences extended beyond technical glitches. Some advertisers began abandoning promotion in Direct and shifting budgets to other platforms.
Restoration is proceeding in stages — first monetization tools and agency dashboards, then, judging by the company's wording, direct advertiser interfaces. Yandex Ads has not yet announced a timeline for the full restoration of Direct and Business functionality.
