AWS use1 reachability 16:11-17:36 UTC 15 Dec
by Phil Lavin 18 Dec '23

18 Dec '23

Hi Folks, Struggling to get any insight on this so hoping somebody else saw something. We lost about 15% of our traffic into our AWS use1 BYOIP ranges on Friday 15th Dec between 16:11 and 17:36 UTC. Customers reported being totally unable to reach us during the window. Unfortunately I didn’t get a trace to an affected customer nor did any of our monitoring tools pick this up. Did anybody see anything at the time and, if so, do you have any insights into what happened? Thanks

Paper available: preprint of research following last year's survey
by Etienne-Victor Depasquale 13 Dec '23

13 Dec '23

I must start by expressing heartfelt gratitude at the amenability of so many people who responded to my request for feedback to a questionnaire I posted last year <https://mailman.nanog.org/pipermail/nanog/2022-July/219870.html>. The results are out and I can share a preprint <https://www.researchgate.net/publication/376111355_A_survey_of_trends_and_m…'_metro_area_network_implementations> . It's long, but the structure of the PDF bookmarks should facilitate browsing to points of interest. Comments and criticism are welcome. Cheers, Etienne -- Ing. Etienne-Victor Depasquale

Outside plant - prewire customer demarc preference
by Sean Donelan 08 Dec '23

08 Dec '23

Of course, every local carrier will be different, what are the current preferences for pre-wiring a customer demarc (NID, the box that hangs on the outside of the house, whatever the service provider calls it now)? 1. Nothing - telco/cable will do whatever the heck they want and wreck the outside of the house anyway 2. Smurf tube from demarc to central distribution point with an interior power outlet near the demarc 3. ANSI TIA-570 prewire (2 x CAT 6, 2 x RG 6) from demarc to central distribution point (low-voltage contractors don't use UV-rated cable for the demarc, and the jacket is trash in a few years) In the past, I found if I made the pre-wire look nice and easy for the field technician, they usually made the extra effort to keep their work clean and tidy.
