My name servers have been running problem free for several weeks now.&lt;p&gt;The Fly UX via the flyctl command-line app is excellent, very Heroku-like.&lt;p&gt;For apps that need anycast the only real alternative to Fly that I found is AWS Global Accelerator, but it limits you to two anycast IP addresses, it&amp;#x27;s much more expensive than Fly and you&amp;#x27;re fighting the AWS API the whole time.</text><parent_chain><item><author>hstaab</author><text>Does anyone here have experience using Fly?
