In some cases it is the ISPs. I'll share an example: Some broadband ISPs struggle with the fact that their customers get compromised and join botnets. Over the last few years UDP has become the ddos attack of choice. Broadband access n

About a month ago their Northern Virginia region was down. All the BGP prefixes associated with it disappeared from the internet (routes withdrawn). This time (I went to check when someone mentioned it) they kept advertising, but all traffi

There's two ways to think about this problem: routes advertised and routes received. Received: So for the most part people implement zero or just minimal filters on routes received from peers. They might drop a set of ASNs they conside

This sort of datalinked network with aircraft up front with radar off, IRST on and launch capability feels like the future of BVR combat. Also add in an awacs to do IFF interrogation and declaring to the launchers as well.

It's a bad movie. The true story is that a company (spread networks) spent many millions building a low latency fiber path between chicago and nyc. Two guys built a lower latency radio network that connected a number of cell towers tog

Juniper MX series. Juniper PTX. Cisco ASR 9000. That's basically a good portion of the internet.

Nanog.org tries to do some outreach. Might be worth checking out some of their intro sessions on the basics of routing, traceroute, etc. Plenty of other resources like irc channels, too.

You have to uncage the seeker head in order for it to track. You would be just dropping it with the seeker pointing forward and hoping that the missile locks onto it with a limited view. The seeker is uncaged normally when you are tracking

From what I read the HARM (and all anti radiation missiles) wasnt particularly good at tracking a moving target. Especially another aircraft closing in fast that is manuverable. As for IR missile options beyond the Sidewinder the US never r

A number of them are. Especially when you get out of first world countries. The problem is that folks who deploy them really hate scaling them up. They believed in IPv6 and the transition isn't going fast enough (sup hosters and cloud

So this is something they're not very open about, but you'll learn the hard way. Years ago Hurricane Electric would setup settlement free peers to be downstream customers in order to inflate their IPv6 footprint. Years ago HE was

Looking at their prefix right now I see them behind Hurricane Electric prepended 3 times. They ought to filter/sever that out give HEs "we treat peers as customers" offensive routing policy. Unless that's what they want

One IPv4 and one IPv6 prefix - no RPKI ROAs signed :(

The anecdote I've heard is that the gear up / low throttle alarm is usually the component to break and people fail to replace it, which leads to gear ups.

Have TKS. I don't believe you can get that on a 172 (but a 182 you can). That said I've heard anecdotally a 172/182 can carry ice better than a lot of other aircraft (I've only been iced up in a 172, never on a Mooney).

Retract on any aircraft is going to drive up insurance.

by kitteh 6y ago
Totally agree with you it's all about what you are looking for (range, payload, power, efficiency). The 172 is a fine trainer, but it really doesn't excel in several dimensions. That may be fine for some folks missions, but for ot

There are several challenges with building a cloud type service in such locations. Connecting it to the rest of the world is one (backbone links, etc.). The other is a very local problem: incumbent telcos who generally have the support of t

Couldn't someone (in the dataplane path) just sniff the knock and observe comms after and replay it later?

In China the cloud provider pricing model is that you have a slider bar to select how many Mbps your instance can scale up (maxes at 100 to 200 Mbps). But that has more to do with controlling customers ability to burst whereas most other pr

While I am not a fan of some of Cloudflares actions over the years, they have been positive in the RPKI space for the last several years. They've hosted multiple meetings in their offices with some of the largest networks in the world

Hurricane Electric doesn't implement RPKI Origin Validation as most people understand it. They try to do some route filtering that is RPKI like, but it's not the same.

You can do this. I know a few large well know networks which have suffered from internal BGP hijacks within their data centers from different business units stepping on each other. You can either try to implement via strict route policies o

IRR has data issues. RIRs put some control around this (tying prefix to org), but plenty of trash in the other IRRs (people claiming they own /12s they don't, etc). Also the chain of people using as-sets to mark who their customer

Eh. There are documented dogfights out there that are dramatic, they even made a show about it with the actual pilots: https://en.m.wikipedia.org/wiki/Dogfights_(TV_series) That said, there are countless stories about
