It's not about the last week only.
Chaos have problems for months now.
I remember how they ignored the issues of mass d/c's and crazy latency. We kept having the issues for months and there were many reports from around EU about this.
Different countries different ISPs everyone got the same issue yet their response on the forums was "everything works as intended no issues at all".
Can't take them seriously anymore.
The problems happen too frequently and the excuses are the same.
Most of time they deal with it by simply just ignoring it.
Meanwhile they responded very fast when their JP servers had issues.
