TAKAWIKI'S CASE OF HICCUPS
The problem is intermittent outages in the network in a large data centre in Chicago, where the wiki's hosting company has several servers. It's not even the data centre's own personal problem — it's further upstream, but they're feeling some of the effects. (I bet this also explains why I couldn't get to Foodler.com the other night and nearly starved.)
The wiki itself is fine, with no data lost, and it seems as though none of the outages have been for longer than a few minutes. If you can't get to the wiki, please just be patient. They're working to get rid of the glitches, and I'll post here again when I receive notice that it's taken care of. I'm sure that will be very soon!
If and when the wiki is down, now or in the future, and you're not sure what's going on, please check the TakaWiki News group on LiveJournal. If there's nothing there about the problem, please comment or email! It may be that you're the first to notice.
