Ok, people. If changing your DNS doesn't work (I use OpenDNS and it didn't work, I tried Google DNS and it didn't work, I tried some public Australian DNS and it didn't work), if flushing cache doesn't work (I did that too), here's what you can try to do if you are a Linux user:
Edit your /etc/host file (as root) and add these two lines:
184.108.40.206 forums.adastrafanfic.com forums
Remember to leave an empty line at the end of the file!!
This manually directs your browsers to the correct IP addresses of the archive and the forum.
I don't know if something like that can be done on Windows, but I hope someone knows and would be able to people know.
