Lag at the same time everyday

Maybe you need to increase the timeout? Try:
tracert -w 5000 63.251.217.2

I don't know what the default timeout is, but I've hit it a few times with ping tests. Lol 2000-3000ms ping times.

(Your bit about monsters not moving for 10 seconds sounds very familiar.)

To see all the command options, type
tracert /?
same for ping test:
ping /?

Interestingly that worked once, but not a second time or a third ect. I tried about five hours later and it still does not work.
