As the lone active administrator at the Vietnamese Wiktionary, I've received several questions from regular users about the wiki's slowness. [1] Part of me wants to tell of the days long ago when Wikipedia used to go offline for days on end due to demand.
Anyhow, I vaguely recall that, at one point, several Asian-language wikis were being hosted or mirrored at the yaseo cluster in South Korea. Is that still the case? At the time, wikt:vi: was still in its infancy, but it's much larger now -- 13th in article size [2]. The idea of a free, community-edited Vietnamese translationary is pretty popular now, and we compete against at least two large projects, not to mention the scores of sites mirroring the same dictionary we imported into our wiki last year. These other projects are all hosted in Vietnam, close to the majority of their users, so speed is a real issue for wikt:vi:. It's what seems to keep many people from using the site on a regular basis.
Users have complained that accessing Wiktionary from Vietnam is pretty slow, and I believe them because it takes relatively forever for me to load some major Vietnamese sites (and I'm on a very fast university connection). If Wikimedia still hosts or mirrors any wikis on yaseo, would it be possible to do the same for wikt:vi:?
