On March 8th, Datadog totally paralyzed around the world and it continued a few days.

I was interested in the caurses of that failure from the point of view of my pure engineering interest. However, Datadog have not disclosed anything yet.

I found two documents analyzed by two authers, so I share the links.

• Importance of Reliability in Distributed Systems: Datadog Outage Case Study
• Datadog Outage: Multi cloud != reliability

I really want to know the caueses of that failure, but Datadog only uploaded the article shown below after 10 days from the failure.
