Microsoft responded by adding server space.
According to developer RedLynx, "The stress on the leaderboard servers became extremely severe late last evening. For a while, the leaderboards were in read-only mode, then couldn't be read at all. Microsoft worked quickly to deploy more hardware and the situation seems to have stabilised."
"Microsoft is now preparing for any more surges in activity that might occur over the next couple of days as more players join the fray, so hopefully no more faultless gold runs will go to waste," the developer added, "We apologise for the inconvenience, and obviously we're working closely with Microsoft's backend team to improve the situation and prevent this sort of thing from happening again."
