I think the point they were trying to make (and it's one I share based upon talking to operators in a few of the largest broadband networks in the US about their usage) is that the WFH crowd is not moving the needle in terms of driving

Disturbing to see. We have the same issue in the US as well. Specifically some companies want NOAA/NWS to give their data to private companies who buy licenses and then the public can go to those companies (ex: AccuWeather). To me, wea

There were parts of our telecom infrastructure that weren't ready but got fixed before y2k. A certain mobile phone switching vendor (think cell towers, etc.) ran tests a year before to see what happened when it rolled over and the whol

The RST cannons still exist and they usually offload that in the domestic China networks to take the load off the GFW. The operators have to pay for them, though :( As for the GFWs tactics they've certainly expanded things into jacking

There is certainly a push to use websites and infrastructure hosted in China. As it's no surprise a number of non-China popular websites don't even resolve properly from a DNS perspective there. So for most of the population the s

There are three main carriers into China. China Telecom (CT), China Unicom (CU) and China Mobile (CM). Each one of them runs their intl connectivity hot during peak hours (they buy from a number of other carriers): in both directions and DD

Was this Rogers New Media? Just curious because my recollection is that they owned the network infrastructure for the cable internet side and were the first folks in Canada to go big on deep packet inspection boxes (aka Cisco pcube, which w

When I worked at a large telco/broadband provider in the 90s and onward such concepts of selling this data was forbidden and you'd get funny looks for suggesting it. Our leadership chain - comprised of a mixture of long tenured em

Plenty of routers today that can't fragment packets. And they have rate limiters where they can only generate a small amount of ICMP 3/4s (maybe 50 a second).

I've heard that the first few years of flightaware they made most of their money in taking requests for not publishing specific aircraft. As for military stuff - they have additional capabilities for their transponders that provide for

Remember that a lot of folks use fractional air charters for their business needs which provide basically no information about whose in the planes. I know of a few large corporations that own their own jets that when they have to go for som

You can register an aircraft to an LLC / company. Doesn't always have to be registered to a person.

Back in the day calea compliance meant you had to provide network connectivity and a signaling mechanism to specify what you wanted to be replicated to you. That meant voice calls and in some cases defining a network acl for packets (I knew

Eh, I know a lot of folks who do enable CDP/LLDP for internal device to internal device links for discovery and troubleshooting. But they don't turn it on any customer/external facing interfaces (this enforcement thru offline

Security best practices have always recommended disabling CDP in an untrusted environment (that applies to things like LLDP, too). It is comical to see how many people leave both of those running on internet exchange points or sometimes wor

It'd be better if they were transparent about it and you could see these actions clearly instead of having to glean it from a looking glass or from in country probes.

Turkey is an interesting country to deal with. For example let's say you are a hosting company in the US and one of your customers is rebroadcasting Turkey television. A turkey govt agency would reach out to you and ask that you termin

Eh to be fair there were plenty of NOTAMs out warning against the routes MH17 was on. However, the amount of garbage in NOTAMs makes it incredibly difficult for people to parse and take appropriate action. There are some great efforts by fo

Given how many other aircraft depart tehran on that same route to the northwest that would be a massive error given how close it is to the airport.

The "hallway track" is honestly the most value I get out of conferences. Talking to others, people willing to share things verbally in smaller groups, etc. Requires some amount of social networking to meet and talk to folks to bui

No active radar. All the tracking pods have FLIR/CCDs on them that allow tracking of objects (which I believe is based upon contrasting white hot / black hot returns). A "point track" for example would allow you to track

Power is involved too. When I first visited a cable landing station I got to learn about the process to de-energize / energize the cable and coordinate with the ship and the remote side. Pretty involved but really neat to see. The stor

This. If you see the oceanic cables every x amount of kilometers you'll see a bump in them: that's the amplifier. There are also junction points too where cables can split off to serve locations on the route. Newer cables have th

The cable landing stations are an easier location to tap the subsea stuff. If you tour one there are rooms they won't let you in.

Underwater volcanoes (rock slides) are the biggest threat to cables when you get into the deep ocean. The cables are much more thin (less armoring then when near the shore). The other fault encountered in the deep (no anchor risk) is from a
