Elite: Dangerous server hiccup left some players unable to log in. If you're one of those players, you might be interested in Frontier's official response which was posted earlier today on the game's official forums.
"We have a server side fix in-place to go live tomorrow, it's just undergoing some final testing tonight and tomorrow morning before making its way to the live servers," writes Frontier's Andrew Barlow. "This should fix it for everyone that's not already been fixed by customer services already. We just want to ensure that the fix is correct and safe so we don't cause more issues for players that are currently unaffected."
