Lemmy.ca not found

Posting from my lemmy.world account.

tried multiple apps, cleared cache, etc etc..

web is giving me a "page not found" error. My existing app (Liftoff) is spinning on a blank page, and new apps (Jerboa and Connect) are telling me that lemmy.ca is not a valid instance when signing in to a new account.

I don't mind being on lemmy.world full time, but if much rather be on home soil. help please?
