Around 7pm last Saturday until roughly 10pm I started feeling a consistent lag in an online game I play. I pinged the game server and was getting request timed out every 5-10 attempts. It happened again on Sunday at around the same time, didn't happen Monday or Tuesday, and happened again tonight at the same time (Wednesday). Pings to Google were fine and didn't seem to experience any issues.
Using a VPN during these times alleviated the issue, but this is not ideal and I shouldn't have to do that obviously.
Every time it would start somewhere around 7 or 8pm and would fix itself around 10pm, and friends were not experiencing the same issues, which leads me to believe it's BT with some form of throttling.
No, it is not BT throttling. It is more than likely simply congestion at peak times.
