rDNS resolution appears to be functioning normally; we will be monitoring this to ensure that the resolution holds.
It may take another 12 hours for DNS to fully propagate but the majority of impacted IPs are delivering email normally.

Update
We are still waiting for the 3rd party to resolve their failed DNS configuration.
Efforts to move affected accounts off of the impacted IPs is continuing.

Identified
We are experiencing rDNS failures related to a 3rd party and are actively working toward a resolution. This affects a small amount of traffic and would look like latency in delivery, or possible failure to deliver over time, for affected accounts. Most accounts are not affected by this issue.
As this is the second time in a short time span, we are moving traffic (where possible) to other pathways while waiting for a more permanent solution.
