It's been like that for a few months now, if you have Ultegra 8 speed bar end shifters (6480), they weren't on the old site (the old site had from 6500/9 speed up, which the new site does as well), and if you got a Octalink BB last week from Niagara, you would have got a hard copy, and you just need to search for the ES** number of the BB, that info is still there.
All the info that was on the old site is still there, + a lot more, although it isn't quite as quick/easy to find some of it as it was on the old site.
Edit, the 8 speed Ultegra info is still there, just harder to find, search SL-BS64 as it turned into a non-series part
