Hi,

I have been selected as the Operational Directorate (opsdir) reviewer for this Internet-Draft. 

The Operational Directorate reviews all operational and management-related Internet-Drafts to ensure alignment with operational best practices and that adequate operational considerations are covered.

A complete set of _"Guidelines for Considering Operations and Management in IETF Specifications"_ can be found at https://datatracker.ietf.org/doc/draft-opsarea-rfc5706bis/.

While these comments are primarily for the Operations and Management Area Directors (Ops ADs), the authors should consider them alongside other feedback received.

## Minor Issues 

There should be some text regarding Path MTU discovery, otherwise it will be left to interpretation. There are also some fuzzy details about server failure modes with regard to malphesense reporting, but that should probably be better defined. Perhaps some further clarification outside of section 8.4 which touches on some of the of failure modes and expected behaviors.
