Dobrý den!
Všimli jsme si (díky Miloši Dlouhému z WIA za upozornění), že naše
IPv6 prefixy (a i několik dalších českých IPv6 rout) jsou předmětem
velkého množství BGP updatů - pro naše tři IPv6 prefixy, které
announcuje AS29134, to dělalo 7-10 tis. updatů v hodině [1].
Koukáním do BGPlay jsem tipnul, že updaty vznikají
periodicky-se-opakujícím přestavováním cest v trojúhelníku mezi jedním
naším upstreamem - AS5588 a dvojicí AS1299 a AS3356. Nepovedlo se mi
hlášením problému skrz zákaznický kanál vyvolat ani po několika dnech
pozitivní vyřešení problému a tak jsem tento upstream v neděli 21. 7.
odpojil, abych stabilizoval své prefixy. Zdá se, že pro nás to pomohlo
- až do okamžiku vypnutí náš graf prakticky kopíruje graf AS5588 [2].
Od vypnutí jsme na několika málo updatech v hodině.
Problém není úplně malý, dokonce se několik českých ASek se dostalo do
TOP 50 nejaktivnějších AS v IPv6 internetu - vizte [3].
Tímto se omlouvám, pokud naše updaty někomu nadělaly nějaké potíže a
zároveň si dovoluji členům této skupiny zdvořile navrhnout kontrolu
jejich prefixů v RIPEstat, která by mohla napomoct k lokalizaci a
vyřešení příčiny problému.
Přeji hezký den,
Tomáś Hlaváček

Hi everyone,
The Network Startup Resource Center (NSRC) is maintaining a wealth of
training material related to BGP, Peering, IXPs, Routing Security etc.:

Hi everyone,
I'm a researcher at UC Berkeley and the International Computer Science
Institute. My colleagues and I are working on evaluating and improving the
accuracy of blacklists. As part of this work, we'd like to hear from you
about the blacklists you currently use, what you perceive as their
strengths and weaknesses, and any thoughts you have on how they might be
improved.
We've prepared an anonymous survey where you can share your views:
https://berkeley.qualtrics.com/jfe/form/SV_200mg5hnQiAOgUl
If you have five to ten minutes free today to fill it out, I would greatly
appreciate your help! Thank you, and please don't hesitate to respond to me
with comments or questions.
(Apologies if you receive this message twice - trying to minimize
cross-posting while still reaching a broad audience)
Best,
Anushah
