Mine's not the case, every time I got disconnected the site you provided told me my internet was fine (tested in NY and CA server). It could very well be and ISP problem, but it would be nice to check if that was the case at least so we can have peace of mind and/or try different things (aka VPN). I don't know if ANet can provide any sort of tool for us to check this, but it would be nice if they acknowledged this issue and try to help us out. All we ask for, really.

Hello, friend. I'm sorry to bring bad news, but this is a well known and unresolved issue from ArenaNet and their servers. Apparently this problem is almost exclusively to NA servers, and people outside NA region. It is getting worse by the day, and it intensifies during weekends, to the point of becoming unbearable to play. There are some attempts to mitigate this issue, but use them at your own discretion. You can find more on this topic here, and in the "Account & Technical Support" subforum:

Today for me has been the worst in months as well, just logging is a miracle in itself. I'm fairly sure it's because of the returning players to get to Halloween event. Anyway, for now, I'm actually avoiding switching maps because I know i'll get disconnected. It really is frustating.

Those specific ones, yeah. The one created May 3rd is still pending.

I'm afraid there's no solution to that problem yet, my friend. I've been getting those for quite a while now and have been nowhere near a resolution. I noticed that this problem occurs more frequently with fuller maps, though it is not restricted to those. Another thing I managed to observe is, you can teleport as much as you like within the same map/server, you will not get disconnected, it happens only after switching maps/servers. If i'm not mistaken, ArenaNet even recognized the issue on a forum post, but they are still working on it, I guess. This is said topic (created May 3rd). Nevertheless, if you can find any sort of solution, PLEASE, let me know. Best of luck to us.
