Interesting one - for the first time in a couple of years using groups.io, I got the message "Your Groups.io Account Is Bouncing".
I immediately used the un-bounce link, and then checked the groups of which I am and owner or a member, and the one that triggered the bounce condition was GMF, probably as a result of a message sent while gmail was out of action yesterday (which made it look like the e-mail account no longer existed).
I joined GMF to learn more about groups.io and its administration, but did not expect practical tests as part of membership!
