The short answer: microsoft Advertising has been highly reliable recently: StatusBird's independent monitoring recorded 100.0% availability and zero major incidents over the last 90 days.
Below is the data behind that answer and how Microsoft Advertising compares to its peers.
What is Microsoft Advertising?
Microsoft Advertising (formerly Bing Ads) runs search and shopping ads across Bing, Yahoo, DuckDuckGo, and Microsoft properties like MSN and the Edge new tab page, plus its Audience Network. Online stores use it for search campaigns and product shopping ads fed by a Microsoft Merchant Center product feed, often importing campaign structure directly from Google Ads. It typically supplies a smaller but cheaper and older-skewing slice of paid search traffic than Google.

What happens to your store when Microsoft Advertising goes down?
An outage can hit the ads.microsoft.com web interface, the Microsoft Advertising API, ad serving itself, or Merchant Center feed processing. If serving is affected, paid clicks from Bing and partner properties stop arriving at the store; if only the interface or API is down, ads keep running but you cannot adjust bids, budgets, or pause campaigns, which matters if a promotion just ended. Feed processing failures cause shopping ads to show stale prices or disapprove products, which can mean advertising a discount that no longer exists.
Typical symptoms during a Microsoft Advertising outage:
- ads.microsoft.com fails to load or shows errors after sign-in
- Traffic from bing.com referrals drops noticeably in analytics
- Bulk uploads or API sync jobs from tools like Google Ads import fail
- Merchant Center feed uploads stall or products show as pending indefinitely
- Reporting shows missing or delayed spend and conversion data

Frequently asked questions
Microsoft Advertising will not load but I have a sale ending tonight. Are my ads still spending?
Usually yes. Interface outages are more common than serving outages, so ads typically keep running and spending while the console is down. Search your keywords on Bing directly to confirm, and try the Microsoft Advertising Editor desktop app to push a pause if you need one.
My Google Ads import to Microsoft failed. Did I lose my campaigns?
No, a failed import does not delete existing campaigns; they continue running with their last synced settings. Re-run the import once Microsoft's API recovers and spot-check bids and budgets to make sure the sync completed cleanly.
How this data is measured
StatusBird checks Microsoft Advertising's status every 2 minutes, around the clock, independently of the vendor. The availability figure counts major and critical outages only; minor degradation is excluded so numbers are not skewed by vendors that report small blips near-continuously. Grades run from A+ to F. See the live numbers on the Microsoft Advertising reliability page and current status on the Microsoft Advertising status page, or browse all 84 service grades.
Know before your customers do
StatusBird monitors Microsoft Advertising and 83 other services online stores depend on, plus your own storefront, every 2 minutes. When something goes down you get an SMS, email, or Slack alert with plain-English context, usually before the official status page catches up.
