velké množství BGP updatů českých IPv6 prefixů

by Tomas Hlavacek

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 Odkazy: [1] https://stat.ripe.net/widget/bgp-update-activity#w.resource=AS29134 [2] https://stat.ripe.net/widget/bgp-update-activity#w.resource=AS5588 [3] http://bgpupdates.potaroo.net/instability/v6-bgpupd.html

[Misc] Research project on blacklists

by Anushah Hossain

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 -- Anushah Hossain, PhD Student Energy and Resources Group, UC Berkeley
