Just a heads-up; we're planning to move the backend hosting for Japanese, Korean, Malay, and Thai Wikipedias from our Korean server cluster (yaseo) back to the main servers in Florida (pmtpa) later this week.
We'll start at about 18:00 UTC Friday evening (1am Thailand, 2am Malaysia, 3am Japan and Korea). It will take a few hours to dump the databases, copy them, and re-import them, but if everything goes smoothly we hope to have these wikis back to read-write sometime late Saturday morning local time.
There will also be a brief read-only period for most of our other wikis when we switch database servers during the import. That should last only a few minutes, and will not affect en.wikipedia.org (which is on a different database server). It should be some time in late evening or night European time.
