I'm the author of this post. If perhaps you're wondering why I didn't just transfer the domain to Cloudflare, it's because they do not support the South African TLD, unfortunately.

I have been with EuroDNS for many years and did at least two registrar changes from other companies to them. Never had any problems.

Have you already reached their support to clarify what was the problem?

Default behaviour in a registrar transfer is to leave the nameservers as is - the rar has to explicitly send a new ns set in the transfer call to effect a change.

Are you positive you didn't accidentally tick a checkbox or anything to use their nameservers?

no problems here

Uh oh. What went wrong over there?

I miss the days when Network Solutions was run by Verisign.
