* If the person who commented got the "too many connections" error when they commented, the job for sending the email was unable to make it to the database and can't be re-sent: you won't get an email notification for that comment, sadly.
* We have another issue that we're looking into that may cause a small subset of notifications to fail, and we haven't fixed that yet. (It's the current thing people are working on.) I don't know for sure whether it will be possible to re-send those failed emails once we fix the problem, because we haven't pinpointed the exact problem yet. It's probably not very likely, though.
