Guild Wars 2

Since patch i’ve been having problems inviting people or accepting invites, it keeps giving me client/server error.
Using wp also sometimes gives me client/server error thingy.

I couldn’t even log in earlier

The game overall , seems slower than usual since the patch.
On 2 different computers and different networks.

What’s strange is sometimes I can’t access the game or forums on my wifi but have no trouble with any other site.
