I don't know if anyone on here uses this service for Usenet access but I 
hope this post will be useful.

They appear to be having some problems as someone else has hijacked their 
domain and it is not possible to access through nntp.aioe.org.

However their test / back-up server aioe.cjb.net is working. Indeed I am 
posting from it now.

Simply replace nntp.aioe.org with aioe.cjb.net in your newsreader. Again 
no user name or password is required.
