Thread: The delayed-list-mail-delivery problem is back

I've been noticing substantial delays (up to tens of minutes) in delivery
of email to various PG lists for the last day or so.  This is quite
annoying while we're trying to get our ducks in a row for a release ...

            regards, tom lane

Do you have an example or two?

I know we have an ongoing network issue in a DC right now which might
affect delivery to the archives (but shouldn't affect user-to-user
delivery), but that has not been going on for that long at all.
