Now after the november patch, everyone suffered from the issue. I highly suspect they have shut down the old servers and switched to the new one completedly. With maybe wrong configurations or something else, the server reached the bottleneck very quickly, then everyone was crashing and kicked out from the server.
Totally a guess without any evidence, didn't inspect the network connections by wireshark before October. Tested to ping the login server `ping 192.99.109.129` and `nslookup a23-221-110-169.deploy.static.akamaitechnologies.com` last month and got a over 50% package loss at that time.
