We've temporarily taken down some of our game worlds due to ongoing issues with our ISP Navisite. We deeply regret the service outage, and as I mentioned before we are now in the process of moving to a better ISP. As mentioned earlier, we have been in touch with the affected ISP, Navisite, to request that they resolve the problem with their routers, but so far they have not managed to do this. As the worlds in question can't be used reliably until Navisite have sorted themselves out, we've taken them offline.
