Outage problems at Bing Ads continue to plague the search engine's conversion reporting platform -- leaving advertisers without visibility into spend, as well as campaign performance like impressions, clicks, and conversions. As of 4 a.m. PST, the incident report shows the system continues to experience a glitch.

Bing Ads issued an apology in forums and on Twitter Tuesday. Advertisers cannot access their data to determine the performance of advertisements, which makes it -- to say the least -- difficult to optimize.

The Microsoft form began reporting a loss of campaign reports Saturday. The outage affects API, Web UI, Bing Ads editor, and mobile.

Initially, Bing reported that users monitoring reporting data may find the business intelligence data did not populate. The data delays affected multiple services across the Bing Ads platform. This issue might also cause over/under delivery due to campaign budget pause or replenishment delays.

Engineering teams are seeing some processing improvements in systems after deploying a fix. As of February 10, 2016, 1 a.m. PST, Ad Campaign performance reporting is delayed by at the most 19 hours -- down from 40 hours earlier in the week, according to Bing.

Bing did confirm that the data processed during the weekend is incomplete, and will update the data for impacted hours as soon as the system catches up.

The Bing shopping catalog, also hit by the outage, experienced roughly the same delay in reporting. Billing information, also impacted, might not show the exact value in the reporting interface as long as the glitch persists.

These are the Bing Ads platforms seeing delays:

• Ad Delivery: Users might see over/under delivery due to campaign budget pause or replenishment delays.
• BI/Reporting: All advertiser facing reports are not populating with most recent data.
• Billing: Prepay and Postpay billing information is impacted and might not show the exact value.
• Advertiser API: Bing Ads Advertiser API customers trying to pull complete data for the previous day with "ReturnOnlyCompleteData=true" could have received some error messages.
• Product Ads: Bing Shopping catalog processing is also about 2 days behind. Bing Merchant Center users will notice that Feed Files uploaded could take up to 2 days to process
• UET/Remarketing: UET tag status for Active tags will be incorrectly showing as 'Inactive' and Goals may show as 'Not Recording Conversions'. Remarketing lists sizes have not been updated since 2/6/2016.
• Publisher: Reports retrieved from the pubCenter UI and the pubCenter Reporting API may not have complete data during the impacted timeline due to data upstream not being available.
• Editorial: There will be a delay in processing Keywords/Ads/Ad Extensions that are in Editorial Pending Review status. Appeals requested through Bing Ads UI will also experience a delay.
