Side effects of HN outage : HN Notify service sending multiple notifications

Now that the HN is up & running again I noticed that the HN Notify(http://hnnotify.com/) service I am using is sending multiple notifications of same comments again and again. Is that one of side affects of HN outage?

Also, out of 7 comments 5 are gone.
