Update: We're hoping to bring our login servers back up within the hour.
Upon login, it's possible that some players may find they have lost up to 15 minutes of progress.
Apologies for the inconvenience, and we'd like to thank you for your patience.
Edit @ 18:40 GMT: We're investigating renewed reports of login issues.
As earlier, we'd recommend avoiding dangerous activities, and world hopping until further notice.
We're sorry for the inconvenience, and we'll update you as soon as we have more to share.
