Public lg's in Hong Kong show appropriate paths (via Japan), but different
providers show different perfomance (from Hurricane's 150ms to PCCW's 200+ms),
not mentioning quite uncommon jitter.

What's up with Wikimedia's infrastructure in South Korea? Is it still up? If
so, is it utilized for HTML caches? What about uploading? (Just a question for
the ops: as a user from Europe, does the file go to the European cluster and
then being proxied silently to the US when I start uploading?)
