When I go to www.registerfly.com it says:

This is the Plesk Server Administrator™ default page.
If you see this page it means:

1) hosting for this domain is not configured
or
2) there's no such domain registered in Plesk.

For more information please contact support@registerfly.com


Is it hacked or bankrupt or something else? If anybody knows something of it please let me/us know.

Hi.

RegisterFly can be temporarily(?) located at RegisterFly.biz . It is fully functional, as I have registered a few more domains within the last few minutes. I believe they are doing some server maintenance, but I forgot what the original message said.

Hope this helps.

Ok..thanks for letting me know :)
