Sounds more like internet issue to me than game issues. Download and install
PingPlotter.
Start pingplotter and you will see something like this (this is an older version I think)

In the red box (adress to trace to) type in this address 71.252.137.154
In the purple box (number of times to trace) select unlimited
In the blue box (trace delay) select 1 second
Hit the trace button and it will populate the right hand fields. If you see any red/packet loss you have some sort of internet issue. If the issue shows up in the first hop or two it could be as easy as resetting your modem and/or router. If it is further down the line, then you may have to contact your internet provider. Post a screen shot here and someone may be able to point out issue for you.
Keep in mind everyones connection should start get messed up as everyone and there brother is shopping and using up bandwidth.
