Guild Wars 2

This is happening to me as well. I can’t load into any of the new zones for longer than a minute before a DC. (Lake Doric, Bloodstone Fen, Bitterfrost Frontier and Ember Bay. I can load in to older world maps most of the time. However, I just tried to zone in to Fields of Ruin and DC’ed after a couple of minutes. East Coast, USA here.

You have to stop attacking/stow your weapon all together once you get a debuff that looks like a red blood drop on a red background. It’s called “Vampiric something”. If you attack with that buff active you heal him. So avoid ground aoe because you cannot cancel it once you start it and you can get the buff at anytime. Our group did this challenge about 6 times with new people joining and nearly gave up. It also seems that ranger pets can get this buff as well so I would recommend putting them on passive and use auto attack and rapid fire. Hope this helps in any way.

Try setting your DNS server to Google in your network settings:
Right click “Network” > Open Network and Sharing Center > Change Adapter Settings
Right click “Local Area Connection” > Properties > Select “Internet Protocol Version 4 (TCP/IPv4)” > Properties
Select “Use the following DNS Server Addresses”
Preferred DNS: 8.8.8.8
Alternate DNS: 8.8.4.4

This solution does imply the the problem is ISP related although for me all 3 different ISPs I tried had the same problem which implies a deeper underlying issue for my loacl services I guess.
I did not come up with this solution, I found it and am trying to spread the good news!

This is a quote from purestorm.4072 and it fixed my problem. Maybe it will work for you as well.

I just changed my DNS preferred to 8.8.8.8 and my alternate to 8.8.4.4 and it worked instantly.
