We have received confirmation: the issue is related to the backbone connection to the data center.
The situation is similar to the previous incident, when a large-scale internet outage in Europe caused several projects, including ours, to temporarily lose access to their servers.
At this point, we have to wait for the connection to be restored. Some players are temporarily able to connect by changing their traffic route— for example, by using E-Net in the Launcheror similar solutions.
We will keep you updated and let you know as soon as we receive any new information.
