@Lithium I checked TGH and Pokemon Trade this morning (9:30). I am still getting spikes every 5 minutes or so when I am the only person on both servers, while maintaining 9ms latency. So as far as I know, the server spikes all day. It definitely gets worse around 2-3 P.M when the population increases. Like @Vexx said, it could also just be TF2 or the TF2 Server software. It doesn't seem like it, but I do not know for certain.
