It appears that comments stopped federating to other instances again sometime yesterday morning (January 5th, before 8AM EST). I can verify that the issue is affecting outgoing comments to multiple different instances (incl. lemmy.ml & lemmy.world) and that it remains ongoing as of the time of writing (e.g.: compare this remote post vs. SDF's copy, my comment is missing). I'll do the honors and ping @SDF@lemmy.sdf.org here and now so you guys don't have to.
In the meantime, since we're all marooned here anyway: how's everyone's weekend been going so far? Any exciting plans?
For context, here are the current frontend (UI) and backend versions SDF is running. Keep an eye out for updates.
