Not sure if it is just me but since yesterday I got rampant disconnects from WoW servers and Battlenet. It come to the point that I don’t dare play anymore since the risk of dying is so high. When I say rampant I mean it is like every 1-5 minutes.
Thats a problem on your end. Give your isp a call and ask whats up.
Yea not really, people were mass dc-ing from some layers/zones just a few days ago, sometimes I was included sometimes not.
Servers are bad, not as bad as they used to be but still, also the login server drops your connection randomly as well.
We have people DCing in Wrath too. Either Blizzard are being DDOSed or the rent a very cheap host for Classic realms.
Not randomly. Every time you not choose other toon or log in for more than few minutes youd get DC. Is not random if happens every time 
Can someone confirm if the disconnects are more possible to happen during world drops?
If this means that you DC more when random good things drop from mob. I can say No, ain’t so. DC’s for me happen most in town, on ship and in flight.
It could be people on the same ISP, like what used to happen with Virgin Media in the UK.
