Pile, if it is still not working then it is probably a DNS problem either with your ISP or GDN's provider (or someone upstream from them).
If you call GDN they will probably say "it works for us", in which case contact your own ISP. Also, if you can try again from work or an alterative ISP.
If you are desperate for previous announcements, post your email address - I have them all...
