i wasnt able to access anything ESO until i have changed my DNS server.
follow this guide step by step and you'll be able to access ESO game and forums, at least that what worked for me.
http://www.howtogeek.com/164981/how-to-switch-to-opendns-or-google-dns-to-speed-up-web-browsing/
i have not chosen google DNS servers as the guide does, but OpenDNS.
Preferred: 208.67.222.222
Alternate: 208.67.220.220
make sure to backup everything prior changing your DNS server
i take no responsibility for whatsoever problems you may come into
hope it works with you aswell.
changing your DNS server is rather easy, and so is reverting the change, so you can do it for "test purposes" in couple minutes.
Edit: I am playing on PC EU.
the fix is potential and not guaranteed.
