Several sites are like this. Weather Underground has been in the process of migrating to a newer code base any day now since IBM bought them ten years ago, and now that they're private-equity owned I expect even more neglect than the two part-time interns IBM had maintaining it. Pity because it's a great site, it's just been running on life-support for a decade or more.

Another one is the TradeMe site in New Zealand, notable for being one of the few countries where eBay isn't dominant. This is from DailyWTF, they've been "doing some upgrades" for forever, every time you hit one of their countless bugs you get a note that it's due to the upgrades that have been going on now since the place got taken over by.. whaddya know, another private-equity firm.
