Have Doughnut and Have Drill were the govt programs (which have been declassified) where we used acquired MiGs to learn their weaknesses. There are some great videos on YouTube and books from people who were directly involved in the Red Eag

Highly recommend folks who are into aircraft warfare pick up a book about how the AIM-9 Sidewinder was developed as a side project at China Lake by the Navy that had to be done under the radar due to politics. It's a great story about

Yes - this has been falling over for the past week.

Problem is they were more specific prefixes for quite a few people and that trumps everything.

ARINs RPKI APIs could use some love, that's for sure.

It's the same event. BGPmon was just delayed by a few days.

Max prefix kicked in and tore down the sessions before that damage started (it's also why it was so short).

IRR contains data - question is can you trust it? RIPE has cleaned up their stuff, sure, but the rest of the IRRs out there haven't. Next question is which IRR once you get past the RIRs? AltDB? There's a few out there. Lots of cr

The challenge is with scale. If I'm a network who has many networks downstream of me I might have 50 to 100 prefix changes in a month. None of my upstream providers are going to like manually vetting all of those - and none of my custo

A portion of the IPs hijacked had ROAs. The real question is how many networks doing RPKI Origin Validation (OV) weren't accepting the ARIN TAL (ignoring ROAs from ARIN) due to their license to provide them indemnity. Remember that RPK

Cogent and Level3 weren't filtering their own customer. This is what happens when large companies say prefix list updates / validation is too much of a burden and allow customers to run bareback BGP. That said, Cogent is going to

There are some geoip databases that will denote if it's end user networks and if it's fixed (DSL/cable) or mobile.

The NANOG community is much better to operate in. You are dealing with your peers (ha) and what you say generally resonates with the audience better. At IETF, you have people who collect paychecks from companies who technically run networks

We can't even get IPv6 everywhere after several decades. We'll be dead before this is a thing (and it won't be).

The IETF is a pita when it comes to the routing area. Operators aren't well represented there and it's vendors running the show (this is why Randy Bush calls it the IVTF, and he's right). I am happy to see folks like Job make

There are people who work in very essential roles (think power plants) who are already facing challenges with COVID right now. Ive heard a few stories about folks at plants where they've divided up teams in ways to prevent groups from

Curious if aircraft have cycle limits due to pressurization, how many cycles do these subs support ?

Problem is you'll eventually reach a point where the problem is deep and requires them to escalate, and if you aren't checking the box of tested customer cpe they'll stop. Example of this is when I found a Comcast backbone li

+1 to init7. They've gone above and beyond when I needed them to change their routing policies to improve end to end latency to a specific destination. Good luck getting that from a major us carrier. And I wasn't even a customer.

Similar bottlenecks occur in FTTx/DSL networks. For example, uplink congestion on a DSLAM or L2 aggregation device.

Another reason: maintaining a supply of chemical weapons is dangerous. Turns out no city/state wants that stockpile, either. Years ago a co-worker of mine at the phone company had to go to military base in Terre Haute to work on some h

Activating the DLA (Defense Logistics Agency) to handle supply control and distribution instead of this states vs. states and states vs. fed gangbang of bidding and suboptimal routing of resources that's going on right now.

This is a accurate explanation. Eyeballs are inbound heavy and have plenty of outbound capacity (it's also why they don't care about outbound ddos so much...). However it's important to remember that they can easily congest t

That's like asking a telephone lineman about IPv6. Diff layer in the OSI stack.

Because the NOCs may not be all that competent. I remember talking to the Cablevision IP NOC back in the mid 2000s about their internal backbone circuits they were running hot that went to a POP we peered with them. I had Cablevision at hom

by kitteh 7y ago
The problem is that most companies aren't going to tell you that their peering circuits are running hot or that their internal network or access layers to the end user are running warm at peak. ISPs all do stat muxing and the line is &

Yes I'm well aware of routers policing TTL=1 packets, but if you see consistent loss all the way down it's usually a sign. This compared to seeing individual spikes on intermediate routers which are usually control plane policing.

Comcast's last mile network in Seattle has been struggling in some areas from the morning until around 4 to 5 PM. It's not massive loss, but enough to disrupt video conference. Run a mtr towards an Internet dest and you'll se
