Yes, #mstdnca had major issues yesterday after a software update (& I think switching some services to Chad's new home server at the same time). The web app is now working today, but federation is definitely on a few-hours delay.
If there's a particular account you want to check for updates, you should be able to see it on the profile on mstdn.ca. Otherwise, we're just hoping it gets sorted soon.
