This problem happened for a week when I upgraded to the new speed. Generally, I play Dota2 in EU West SV. and ping should be 40-60 ms. However, after upgrading a package, every night after 8 pm when I played Dota2 the ping went from 40 ms to 1000-2000 ms. I had asked the technical team 4-5 times but they can't solve the problem, any help ?
I'm sorry to read that you're experiencing high pings during the evenings.
From checking your connection, the downstream power levels are too high. As this can cause an impact on your broadband, I would like to book an engineer to adjust these for you. I've sent you a PM (purple envelope icon, right corner) with some details for you to confirm please. Once you have replied I can go ahead with the appointment.
