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!

Same thing happened to me - the trigger was also GMF.

Janet,

It was not the gmail problem from yesterday as the list of my accounts
bouncing went back to messages from the time of the transfer in.

There definitely was an event yesterday afternoon, 2 to 4 pm Pacific (22:00 to 24:00 UTC) which put a couple hundred GMF members who use Gmail, myself included, into Bouncing status. Gmail was reporting that those addresses did not exist.

Mark reported in beta that the issue was not only site-wide, but was affecting many other email services as well.

I haven't posted messages to some of those in months niow and yet they
were on the bounced list.

You posting isn't the trigger. The trigger for the Bouncing status is whether Groups.io (any group) tried to send a message /to/ you.

It stands to reason that the more active a group was during that period, the more likely that group would be the one cited as causing your email address to go to Bouncing status.

Shal,

If someone is on a number of very busy lists, this would seem to make
bouncing more likely due to the amount of traffic going to one account. At
least I think that's the issue for many of us Spectrum/Charter users. But
the message logged shows an explanation that clearly say the issue is
Groups.io is sending or connecting too many times and needs to throttle
back. It would serve as a clue that would impact many members as I guess the
threshold is for all of Groups.io mail servers talking to the
Spectrum/Charter mail servers. I hope the solution they are working on is
taking that into account.

Setting a number of members to bouncing is only a temporary and poor fix as
that reduces the continuing traffic from GIO to Spectrum/Charter.

Ken,

If someone is on a number of very busy lists, this would seem to make
bouncing more likely due to the amount of traffic going to one account.

Correct, in the sense that each message sent is an opportunity for the receiving service to reject ("bounce") one of the messages.

In the case of yesterday's Gmail problem, someone whose group subscriptions sent no messages during the affected interval would not have been put on Bouncing status.

But the message logged shows an explanation that clearly say the issue is
Groups.io is sending or connecting too many times and needs to throttle
back. It would serve as a clue that would impact many members as I guess the
threshold is for all of Groups.io mail servers talking to the
Spectrum/Charter mail servers. I hope the solution they are working on is
taking that into account.

For that circumstance, yes. Several months ago Mark implemented means to regulate how many simultaneous connections Groups.io forms to any given service, and IIRC how many messages to deliver during each connection. So it should be a matter of tuning those parameters to suit the limitations of a given service, while working with the service to increase what they allow if their limits are causing noticeable message delay.

Setting a number of members to bouncing is only a temporary and poor fix as
that reduces the continuing traffic from GIO to Spectrum/Charter.

Setting the individual accounts to bouncing is not intended as a fix - it is a response to the service's rejection of messages. If there's a large number of rejections from a given service what has to happen from there is an investigation into the underlying cause, hopefully with the cooperation of that service.

In the case of Gmail yesterday the cause appears to have been a temporary failure of their email servers to recognize valid destination addresses.

There was also yesterday a listing by SORBS (a blacklist service) of one of Groups.io's outbound servers as being a spam source []. That may have caused some email services to start rejecting messages from Groups.io rather than simply diverting them to the member's Spam folder.

Shal, I haven't read other posts, just yours, but I just got the bounce message for one of my groups.? I went to the group to see what bounced, and she reported hundreds of messages bouncing, all gmail.? I sure hope Mark can fix this.? With yahoo closing, I would assume he knew what was about to happen here and had prepared for it.? First time that's ever happened to me in gmail.? Not good.
