I haven't read the article yet but the problem I had back then running into UDP with DNS on K8S is that it might consume the UV thread pool and exhausted it. There is only 4 UV threadpool, and DNS resolution use it. When using service with low ttl or if for wahtever reason bug or something and if node has to resolve DNS every time under highload, it's very quickly consume all of thoese 4 UV thread pool.
