As stated in the post I made (Repeated disconnections ) it clearly is a problem with the one of the nodes between Latin American connections and the WoW servers, since after using a VPN (lent to me by a friend) located in the US the disconnection problems disappeared.
Not to mention that the only change in my addons before all this started on Thursday was the DBM update… but I tried with a character that doesn’t have that addon enabled and even then I was disconnected promptly.
Also, I think it’s naive to suggest us to contact our ISP if there’s people from many countries having the same issue: Chile, Colombia, Peru, Bolivia, Brazil, etc…
I don’t think it’s a coincidence.
