^this. 100x this.

I have done a lot of digging around as I suddenly started having large lag spikes and missed packets (also causing me to DC) at very regular intervals post December update. There are forum posts all over the internet on various sites about this, I haven't seen an SE representative responding to any though. The majority of people experiencing these issues seem to experience a large improvement using a routing service (which can bypass said Level3 backbone).
