This is not on your end, it's on theirs - there are about a dozen threads about this already on the Bug forum, the Q&A forum, and the main Technician's Corner forum. It's affecting the game and the game-related sites, and only affecting certain users.
The issues with the Wiki & GW sites, and the login issues some users are experiencing, are both caused by the same issue - and it is a problem WITHIN their servers.
In order to circumvent the problem, you have to change either your origin, or your destination, or both.
Imagine you want to drive from Chicago to Detroit. If you know there are major problems on one highway about midway there, you can either change where you start from... NYC instead of Chicago... change where you're going... St. Louis instead of Detroit... or you can change the route you take from Chicago to Detroit.
You can change your origin, at least as it relates to the sites, by using the Internet Archive
Wayback system... when you try to access a page they have not cached, it grabs a new snapshot of the page. You're actually able to navigate from there, because it's all filtering through the IAW system, and thus originating from their location, not yours.
With the game itself, you have to change your origin to change your destination... if you can log into the game from somewhere other than where you currently are, you can then move to the European districts. That changes your destination, and allows you to move around the "road blocks" currently stopping you from going from Chicago to Detroit.
Until they either fix the roadblock... or you can get it so that you're loading into a different server cluster (Europe instead of America... International is apparently having issues all its own)... this issue isn't going to resolve. They only just started admitting there IS an issue at the end of the work week, which kind of pisses me off since it was happening all week long... but it is what it is.
