I am not normally supporting a heavy hand in regulation, but i think it is fair to say Noction and similar BGP optimizers are unsafe at any speed and the FTC or similar should ban them in the USA. They harm consumers and are a risk to national security / critical infrastructure
Noction and similar could have set basic defaults (no-export, only create /25 bogus routes to limit scope), but they have been clear that their greed to suck up traffic does not benefit from these defaults and they wont do it.
Following a large scale BGP incident in March 2015, noction made it possible to optionally set the well-known NO_EXPORT community on route advertisements originated by IRP instances. "In order to further reduce the likelihood of these problems occurring in the future, we will be adding a feature within Noction IRP to give an option to tag all the more specific prefixes that it generates with the BGP NO_EXPORT community. This will not be enabled by default [snip]" https://www.noction.com/blog/route-optimizers Mar 27, 2015 Due to NO_EXPORT not being set in the default configuration, there are probably if not certainly many unsuspecting network engineers who end up deploying this software - without ever even considering - to change that one setting in the configuration. Fast forward a few years and a few incidents, on the topic of default settings, following the Cloudflare/DQE/Verizon incident: "We do have no export community support and have done for many years. The use of more specifics is also optional. Neither replaces the need for filters." https://twitter.com/noction/status/1143177562191011840 Jun 24, 2019 Community members responded: "Noction have been facilitating Internet outages for years and years and the best thing they can say in response is that it is technically possible to use their product responsibly, they just don't ship it that way." https://twitter.com/PowerDNS_Bert/status/1143252745257979905 June 24, 2019 Last year Noction stated: "Nobody found this leak pleasant." https://www.noction.com/news/incident-response June 26, 2019 Sentiment we all can agree with, change is needed! As far as I know, Noction IRP is the ONLY commercially available off-the-shelf BGP route manipulation software which - as default - does NOT set the BGP well-known NO_EXPORT community on the product's route advertisements. This is a product design decision which causes collateral damage. I would like to urge Noction to reconsider their position. Seek to migrate the existing users to use NO_EXPORT, and release a new version of the IRP software which sets NO_EXPORT BY DEFAULT on all generated routes. Kind regards, Job
