I've been playing on the same server for about 4 or 5 weeks now.
Today me and my friend logged on to play some dayz and he soon after logging on went and looted a city.
While he was looting he tried to get into a garage while a zombie was aggroing onto him he got a massive lag spike and died.
This has happened to me countless times being unable to fight back because the server is so laggy.

My internet connection isn't the greatest but it can run most other games just fine (Gta v among others)
