The PC-specific maintenance is complete. However, the Daybreak group that manages login auth and the other central services for ALL Daybreak games is running longer than expected. There was also a miscommunication that the impact their maintenance was going to have on our PC/PS4 Live servers, which is why our downtime notification didn't include the bit about logins being impacted outside of our planned maintenance window.
And yes, I believe I am throwing them right under the bus.
u/jgolenbo and I are going to follow up with them after their maintenance is complete to ensure that easily avoidable scenarios like this don't happen again.
I'm sorry for the disruption.
