Thanks for the heads-up! HN Replies is up and running though, and notified me of a test comment I just made. If anyone would like to troubleshoot their subscription, feel free to email me.
Thanks for replying! Is the email necessary? It seems it's at least affecting 2-3 folks who replied here, so if you might be able to just look into email sending/delivery for us, that would be wonderful.
I sent you an email. Notification emails through the service seem to have stopped on my end on or around the 13th, if that helps, though I don’t post every day or get replies every day.
