NANOG’ers:
Steve McManus of Akamai and I have a few questions regarding how providers use
time zones for billing, and how the 95th percentile (95/5) is calculated.
Many ISPs use UTC on logs and such for reasons which should be obvious. But do
they use local time for billing? What if there are ports in multiple time
zones? When calculating 95/5 for LACP groups, is the aggregate used or
individual physical ports? Etc.
We have created a short form to collect some real-world data on this.
https://goo.gl/d1HRNb
We fully understand this is far from a statistically randomized double-blind
survey, but it is what we could do in the few minutes of spare time we had.
The form is only 7 multiple-choice questions, with two optional “comment”
sections and an optional contact info section. We would really appreciate if
people would share data (anonymously!) on how they bill or get billed.
The form is designed to be used once per relationship. If you have two
upstreams who use two different billing methods, we would greatly appreciate if
you could fill in the form twice. It seemed easier to have you click 7 radio
buttons twice than ask you to explain the different methods on one form.
Thank you for your time. Results will be aggregated and published at some later
date to be determined. If you would like the results faster, be sure to leave
your email address in the contact section.
