Guild Wars 2

Hi, I have recently started getting the error 5:11:3:159:101. I had it a couple of days ago when leaving an instance, and noticed it did a mini roll back before allowing me to play the character again. Most recently it happened when travelling between Gandaren and Lornar’s pass during the loading screen this time on a different character. Again when I log in it goes to Gandaren loading screen then straight to Lornar’s pkittening screen trying to roll back. I can still log into other alts no problem.
Last year I finally qualified as a Cisco Engineer, which is basically a server/routing engineer and am currently studying the finer points of coding. I read Matts (Anet) reason for the error being ISP packet drop problem and thought hmm interesting since I can log into other characters. I decided to contact my uni tutor who looked at the footage I took of the DC happening, and showed him ping result I took before and after. His unbiased and professional opinion is that Anet need to take a look at their servers as the problem is with their servers not handshaking correctly and drop out being caused there!
I also spoke to several engineers working for Virgin Media (who are also my ISP) who I know through my studies, they have looked at the results and also state that it is clearly an Anet problem.
So the result is, don’t start messing with you system doing client repairs, if it was your client then you couldn’t log into any character. Don’t bother contacting your ISP to complain, they are sick of hearing it, and will do nothing. DO contact Anet using a ticket and complain to them. After all, if your PC wasn’t working but everything else in your home was, would you blame your electricity company?
