Ad requests are taking a long time to process and some may fail to return ads to the client browser due to the connection timing out. The source of this has been identified as a failure in DNS lookups that is caused by a CloudFlare outage (https://www.cloudflarestatus.com/incidents/28r0vbbxsh8f). We have taken action to prevent these DNS timeouts from impacting the ad request processing. The CloudFlare issue has been identified and is being resolved by their engineers.
