   We have identified an issue with an upstream email provider resulting in some posts not being delivered to the full intended subscriber list. It is effecting ~20% of large publications with an average impact of a 4-8% non delivered rate. We are working with the vendor to resolve the issue and will deliver all posts to impacted subscribers.

   Our email sending provider identified the root cause as a bad deploy on their end, which they reverted ~40 minutes ago. All posts are sending successfully, we will continue to monitor closely over the rest of the day.
