I was able to get in first thing after the update. Launched, scanned the system I was in, went to turn in, server crashed. Unable to get in since. None of my squadmates have been able to get in since about half an hour after the update finished. Start is grayed, can't get in. Start is enabled, ship wireframe spins a bit, then get the error connecting to the server.
This update is going as smooth as expected. Maybe tomorrow. Meanwhile, I think X4: Foundations is calling... yup I can hear the servers humming from here... Later Daze!
