We've now moved
ms.wikipedia.org,
th.wikipedia.org and
ja.wikipedia.org to
the Yahoo cluster in Seoul. With the addition of ja, it's now getting most
of its planned traffic share, there's only a few other small wikis which
could potentially be moved. It's dealing with the load quite well.
A few teething problems were reported, and there might yet be some to be
discovered, but for the most part, it's working as planned.
