Re: TLS access Re: Call for Community Feedback: Retiring IETF FTP Service

[Keith Moore <[e-mail]>]

Again, I find this analysis flawed to the point that it's useless or 
nearly so.

The first rule in reporting stats, at least if you want them to be taken 
seriously, is to describe the methods and results separately, and 
separately from any conclusions.

The sampling period is far too short to be meaningful.   If there were 
only 91 unique users for a whole year, that's very different than only 
91 unique users over 12 days.   But 91 users (if they're  IETF 
participants) would be a significant fraction of active IETF participants.

Relationship between FTP and HTTP traffic volume seems irrelevant.  
Again, traffic volume is not an indicator of importance.   So why keep 
citing it?

The conclusions made e.g. "99% of all FTP traffic.." are almost 
certainly not warranted by the raw data, but the raw data aren't 
reported (not even anonymized, not even in summary form).
