As of 03:44 UTC, engineering resolved underlying DNS issue which caused this incident. On-going impact has been improving as DNS cache clears via normal TTL propagation or DNS flushing. As of 04:30 UTC, DNS resolution response was largely recovered globally and will continue to improve as remaining TTL's expire and refresh cache.

Starting at 00:15 UTC, the Dyn Managed DNS service began experiencing DNS resolution degradation and failures to load the Managed DNS portal. Impacted customers would observe DNS timeouts, SERVFAIL or latency during DNS resolution. Customers attempting to access the Managed DNS portal would observe NXDOMAIN or 5XX errors. Our engineers are actively engaged in fixing this incident.
Additional impact: Customers attempting to send or accessing reporting via Dyn Email Delivery API or SMTP may also experience call failures that may work on retries related to DNS resolution failure.
