Periodically, the same symptoms occurred on Asian servers. However,
Blizzard is not dealing with the cause of the problem.
The server is expected to take 10 to 14 days to recover.
I don’t know if the problem with the EU server is the same cause.
The cause will not be removed.
In other words, the same problem will happen again.
Some people say that there is no developer in charge,
which means that this forum page is meaningless.
Still, please keep writing.
One day someone in Blizzard will realize the seriousness of the problem.
