Heres my interpretation on whats happened with these companies.
1. Both relatively small companies (employees -- few).
2. Both taking a regular but small number of orders a week.
3. eservers.biz teamup with hostmania for datacentre.
4. For some reason both (or just hostmania) receive an excess number of orders in short time.

5. CC provider gets worried at sudden increase of amount going through, and halts payments - trading limit exceeded? (until satisfied no fraud).

6. Hostmania suffer loss of domain name.
7. Hostmania get bad components delaying server builds.
8. Provision system goes down due to loss of domain name (not sure how thats linked but....)
Not defending this, but this happens to every company when orders exceed predictions. I live in the UK and have seen it happen to companies as large as BT (UK equivalent of AT&T).
Trouble is at this point do you admit that you are a small company overwhelmed, or try and handle the "gold rush".
Unfortunately unless you can clear up the rush this is what happens.
We all react differently. I have a problem with hostmania not updating us in a timely manner -- but I can understand (or try to) why they may have not.
We all are human, and make mistakes. Time will tell if they are okay or out on a limb. Also I note hostmania has suspended taking new orders (bout time) to clear up current orders.
If you can't wait (and I almost gave up too) both companies seem prepared to refund if asked.
