Yeah Dav, it is probably related to this:
For Oceania
We have identified a vendor who will allow us to support Ultima Online in an environment within Australia. However, it will be necessary to test and setup all of the customer support tools, and account information communication before finally moving the shard. Also, for the new location in Australia, we need to make certain you will get acceptable and playable pingtimes.
In the interim it will be necessary to host Oceania again in California for a short time. We do not expect the transition to take longer than two additional weeks from the beginning of Asia Pacific server migrations. Thank you for your patience during this transition.
