As you can easily see when you visit LessWrong.com, the site transfer is complete, and we are now on the new URL. The data import will run for the next few hours, and by tomorrow morning everything should be complete.
Let us know if you run into any problems, find any broken links, or anything of that sort!
Some old links (e.g. from googling for things) are broken: https://www.lesswrong.com/lw/o5f/wireheading_done_right_stay_positive_without/
Given that this is a major way people find things (coming from google, including trying to find old things they remember), I'd try to fix this when possible. (Though ignore if this is just related to other people's bugs)
Ah, it looks like we broke some of the old links to link posts. Will fix this ASAP.
