Did anyone else receive a Marketo campaign failure notification on 5/14 for your lead lifecycle model? I reviewed the campaign and it seems to be operating as expected. I'm trying to see if it was just me or if others also received the error message and how they resolved it.
I saw a similar post from a member of my network about this (not on the community), there was an outage on the 14th that impacted campaign processing. This may be what you experienced.
