Updated as of 15:45 GMT - 28th March
18:43 GMT: We're investigating login issues. If you're currently logged in we recommend avoiding world hopping and dangerous content.
19:58 GMT: You should be able to login again. Our game worlds were subjected to a sustained attack. We've had to temporarily add some harsh restrictions when logging into the game or world-hopping repeatedly to help mitigate such attacks. If you're unable to login to the game as a result of these restrictions we recommend waiting a short period of time before trying again.
21:32 GMT: We're investigating a recurrence of login issues. We recommend avoiding world hopping and engaging in dangerous content.
22:30 GMT: You should be able to log in again (though the same login and world hopping restrictions detailed above do still apply). This article won't be updated overnight, however if any issues emerge then rest assured that there is 24/7 coverage in place to escalate and resolve issues which arise. We'll update this article over the weekend as is needed.
15:05 GMT - 28th March: We're aware that the problems have returned, as the game worlds remain under attack. We'll continue adjusting the restrictions added yesterday, so as to mitigate this and let you back online as soon as possible. We do appreciate that the restrictions on world-hopping are extremely disruptive to many activities, and we hope to be able to get a less disruptive form of protection as soon as possible.
15:45 GMT - 28th March: You should be able to log in again. When hopping worlds a warning message will appear (shown below) which explains that the login restrictions may result in you being unable to log in for a while. Again, we'd like to reiterate that we do appreciate that the restrictions on world-hopping are extremely disruptive to many activities, and we hope to be able to get a less disruptive form of protection as soon as possible.
We thank you for your patience during this time, and we'll update this page if we have any more news to share.
