After 15 years mydomain decided that my email address associated with the domain was not validated, so they placed the domain into "clienthold" status, which means all DNS entries are removed and it does not function at all. Now, the email address associated with this website was also 15 years old and out of date, so there was no easy fix to get it back online. There was zero correspondence to the account email (which was correct) warning of this.
Their backend hardly functions, you will find it timing out quite often and details not updating.
I would stay the hell away from mydomain, they are extremely incompetent and no one should put something as important as a website in their control, they will only ruin it.
