Currently experiencing missing/incorrect images in navigation and posts

Is anyone else experiencing this currently? Is there some scheduled maintenance occurring that I overlooked? My avatar at the top right is not loading properly and the icons for the search bar and menu are intermittently disappearing, even though the links are still working.

Looks like even more SVGs for navigation elements are now missing too…even here in the post editor…and I can’t attach a screenshot…the upload just fails.

And I also just noticed that some uploaded images are missing (broken links) from people’s posts even though the rest of the content is still visible.

I do not have any adblockers or extensions currently enabled that would affect the site.
