Re: Do people even read these? Re: BGP Update Report

Hello Geoff and all,

Thank you for pointing it out, I must say I don't read many of the until
you brought this up.

I also wonder if someone is seeing what you have mentioned. Again, this
week shows similar thing with these updating about two-times per minute:

TOP 20 Unstable Prefixes
Rank Prefix             Upds     % Origin AS -- AS Name
 1 - 93.181.192.0/19   22303  0.6%   AS13118 -- ASN-YARTELECOM
Verhnevolzhsky branch, RU
 2 - 110.170.17.0/24   22036  0.6%   AS134438 -- AIRAAIFUL-AS-AP Aira &
Aiful Public Company Limited, TH
 3 - 103.242.52.0/22   20105  0.6%   AS131390 -- ECOMVIET-AS-VN Vietnam
E-commerce Development Centre, VN


As you have mentioned that generally no more dampening. It would be nice if
someone could contact these operators and let them know. Is there a
mechanism in place in contacting the admin of these AS/prefixes or their
upstream? Should there be one?

I also wonder about the general cause of these high-frequency updates. Is
it from router processing overload, bug in the router, simply poor
connectivity or other reasons?
