1 .. That sucks big time!!
It may do so but uCoz are not at fault in relation to this issue. Your provider (Comcast) have blocked the server from their end and unfortunately there is nothing we can do at our end to speed this process along.
2 How about a new site on a different server? When I try to create a new site, it still gets created on server 57. Can you create a site for me on a different server???
This is a default process built into the system. I will leave this up to Sunny but as far as I am aware it is not possible to get around the auto-designation of servers.
