That's more or less the time it takes to test the patch and for cloud providers to apply the patch so there isn't large-scale mayhem.

Two to three Tbps aggregate won't change much except maybe for islands that are currently dependent on VSAT.

Nexus 9000, running ACI, not normal NX-OS, as opposed to the ASR 9000 series which are common internet routers. Cisco model numbers are fun.

It's still a bit editorialized since this only affects ACI mode, not the default (and far more common) NX-OS mode.

I suspect the nuances, attacks, and mitigations around this would be a good topic of conversation at a conference or something if we ever run into each other. Unfortunately there's not much that one can say in public around specifics o

You are talking about one 100G circuit and the relatively minor sever+tap costs. Summary of metadata might be possible if they have a small number of selectors pushed out to the edge, but given the footprint of a FAANG backbone and edge pop

IME you are served a subpoena to testify to specific information that they think you have, and if you can provide it prior to the date of testimony, you don't have to show up. Suspect a warrant would be if they wanted to take something

The ones you cite are hardly reputable journals, and are disregarded because they are junk science, not because of politics. In "Brown", the paper was misrepresented as a study on trans people, when it was actually a survey of par

That's a pretty misleading representation of the state of research, unless journals like nature, endocrine society, neuroendocronology etc are now politicized social sciences.

This reads like a traffic targeting system ala FB's cartographer (c10r) bolted onto an ad exchange (continuous bidding etc.) Interesting to see if they can keep the 10-second update intervals while scaling to more users. Curious to see

Companies already can have their own 4G networks in factories etc. It's fairly common in mining or oil fields. There have been wireless access platforms with much more control over latency and robustness for well over a decade. Bandwid

This is less about cost of bandwidth and more costs of having edge POPs around the world. With cloudfront (or any other edge cache system), you get TCP termination closer to end-users so the site loads faster, particularly if you have users

It’s about the same, really, both in severity and impact to users. Routers fall over pretty regularly if you have enough of them so you already have things like MPLS FRR to deal with that. Sounds like this is for netconf, which is a provisi

You don't actually know if something works until you've tested in prod. Adding some community tags to BGP announcements is really trivial and mostly harmless.

Shifted from hardware intensive (ASICs, FPGAs) to software so we can do high-speed packet mangling on commodity hardware. Initially pretty involved with DPDK etc but much easier as of late with XDP+eBPF. e.g. https://jvns.ca&#x2F
