If you want to know if it's only your connection or provider or if the EAB server makes this trouble go to a http proxy like:
http://anonymouse.org/anonwww_de.html
http://www.guardster.com/free/
and try EAB from there. Btw, today I had some problems with Aminet and the same happend via these proxies, so my connection was ok.
