Investigating

We are currently investigating an issue where certain domains are not resolving as expected. Initial analysis indicates that this behavior occurred because the domains were included in the security feed, which temporarily impacted their resolution.

The domain a01.azurefd.net was present in the feed and has now been removed. If you continue to experience resolution issues for any domain, please follow the steps in the article below to add the affected domains to a custom allow list:
