We were able to combat the lag issue by using a VPN service such as Spotflux (which is free but seems to cap your dl speed at 2Mbps). Alternatively you can use a paid VPN such as PureVPN which we use anyways because we are overseas and want to watch netflix & Hulu w/o having our connection speed capped.

Since using spotflux/PureVPN we have had 0 lag spikes. ZERO! None! zilch!
I understand that the issue still has something to do with SE, and they should fix their issues, but in the mean time this is a temp fix. Try a VPN and see.
