I have been getting ping spikes in games such as Counter Strike: Global Offensive and Battlefield 4. This happens every time I play any online game. My 'playable' ping is usually roughly around 50-70 ms. However, I get ping spikes of up to 600 ms every 2 minutes.
This is literally unplayable for me and I unhappy with the service that I have been provided with.
I used to be a sky customer. Whilst their speeds were lower, the ping that I would get on their service would be better, by far, when compared with the ping I get on Virgin Media.
