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!
Two post-migration issues:
Login for legacy LW1 users now seems to be totally broken: a user error “LW1 user detected, legacy salt attached” shows up in the JS console (and appears immediately on GreaterWrong) but nothing further happens.
The third party site GreaterWrong doesn’t seem to be showing updated karma scores or recent (newly-imported) LW1 comments in its user profiles, although these do appear on LesserWrong.
Fwiw it's "caching" not "cashing"
