Every 10 or so seconds the game stutters for around ~1/4-1/2 of a second, sometimes it doesn't happen for a minute but othertimes it happens every couple of seconds. It has been happening for months and it's not a server specific problem as it occurs on both EU West and EU East.
Welcome to the community I'm sorry to hear that you're encountering stuttering in DOTA 2 & CSGO. I can imagine how frustrating that must be right now. I've run some tests and I don't see any problems with either the hub or the network segment. Are you using a wired or wireless connection to the hub? Does this only seem to happen at certain times, or constantly? Could you post some ping & trace routes to the affected servers in router mode and modem mode please? Post your results here and we'll take a look to see where the problem is occurring.
