AdInsight - Could not resolve host

Question

I'm making a call to GetAutoApplyOptInStatus and this was working yesterday, but doesn't work today. The error I'm getting is:

SOAP-ERROR: Parsing WSDL: Couldn't load from 'https://adinsight.api.bingads.microsoft.com/Api/Advertiser/AdInsight/v13/AdInsightService.svc?singleWsdl' :  
failed to load external entity "https://adinsight.api.bingads.microsoft.com/Api/Advertiser/AdInsight/v13/AdInsightService.svc?singleWsdl"

I checked it with curl:

curl -I "https://adinsight.api.bingads.microsoft.com/Api/Advertiser/AdInsight/v13/AdInsightService.svc?singleWsdl"
curl: (6) Could not resolve host: adinsight.api.bingads.microsoft.com

But the Status page shows "Ad Insight API" as "Good"

What's going on? Is the status page manually updated, and nobody has realized yet that the Ad Insight API is down?

Answer 1

The issue appears to have been resolved over the weekend. Tested a couple of API calls to the Ad Insights API, and they worked.

Furthermore, the following HEAD request:

curl -I "https://adinsight.api.bingads.microsoft.com/Api/Advertiser/AdInsight/v13/AdInsightService.svc?singleWsdl"

now returns this

Answer 2

We're experiencing the same issue as above.

The domain

adinsight.api.bingads.microsoft.com

as referenced: https://learn.microsoft.com/en-us/advertising/guides/web-service-addresses?view=bingads-13

cannot be globally resolved:
