Are you still observing this?
I’m not familiar with the dig tool, but things are working alright for me. I’m also not hearing about similar issues from other people. Is it possible that this is related to DNS resolution in your region or the particular network you were using at the time?
I’m not a major expert on DNS stuff, but nothing has changed on my part, so I suspect any issues are from some intermediate provider or resolver or something like that. Would need more information to be sure though.
Would something like that explain what you observed?
Note to general reader: I very highly recommend that people cache ~/.elm/ on CI so that they are more resilient to downtime of Elm websites or Github or whatever else can go down. The elm binary should be able to build a project without an internet connection as long as ~/.elm is preserved and your deps haven’t changed since you last had a connection.
