I keep asking myself why they don't start using a more traditional domain in order to avoid these types of errors on the user's side.
For example, this one is still free: exch.services
Apparently it will be "exch.net" (at least if their plans did not change since).
They wrote about their domain name change some months ago:
Last week you made changes to your OP and pointed all links to the .pw domain. Will it remain like that from now on?
We will soon be migrating to the `exch.net` domain we bought for 10k$ so I don't feel any urge updating the OP right now and think it's better to update it when we perform definitive changes.
We bought the .net one because .net, .com and .org zones are those of very few left that are not managed by any centralized authority, unlike most ccTLDs today that were bought by corporations like CentralNic who can do whatever they want with the domains independently of the company that sells them.
I no longer remembered that.
Now, I don't understand the delay. Are they preparing some kind of update, and releasing everything at the same time?
