The surprising omission from this post is that it doesn't conclude with them migrating away from 101domains. Comically bad support and not paying registry fees. I'd have pulled domains the moment it was live again.
In any case. I was very surprised that they were using such a registrar in the first place..
As a startup, I understand. But after you've got a round of funding or two. Move your domain to a company with a decent reputation and support.
What was your bad experience with 101domains?
