Na Diablofans je toto, predpokladam ze su to dve spravy a ta druha hovori ze by to uz malo byt ok:


We're currently investigating reports of login issues both to Diablo III and Battle.net in general.

In order to look into this can I please request the following info:
ISP :
Town and Country :
A pathping to your region:
battle.net/support/article/running-a-pathping-test
And a trace to your region:
battle.net/support/article/performing-a-traceroute

This info will be forwarded on for investigation by our networking team and we'll update here as soon as we get more info on this.

Thank you for your co-operation.

Thanks again for your patience.

We were able to resolve the issue so players should be able to log in now. There may be a rush of players accessing the logon servers please wait a few minutes between attempts to get in game if you still see an error.
