It would appear that large chunks of TATA in APAC are unreachable from Cogent now, by the looks of it due to Cogent depeering TATA in APAC.

Networks that are single homed behind AS6453 (At least in APAC/India) or AS174 will not be able to reach each other. This is similar but more serious to the previous regional NTT-Cogent depeerings (since those ones were just in the Europe region, and raised latency instead of full unreachability)

This seems to come off the back of Cogent trying to establish a market in APAC, and the main players in that region not wanting to have their market eaten away by Cogent (To be fair, Cogent is very good at getting prices down, and APAC is still quite expensive per mbps).

A snippet of a Cogent ticket says:

Despite Cogent’s repeated requests, TATA has consistently refused to establish connectivity in Asia, taking advantage of Cogent’s good faith efforts while also ensuring sub-standard service to both companies customers. No amount of good will and good faith augments on Cogent’s part has brought TATA any closer to the negotiating table for a resolution to the lack of connectivity in Asia. This one-sided situation has become untenable and as a result, Cogent has elected to start the process of restricting connectivity to TATA.

Estimated damage is that 1575 ASNs now have (more) connectivity issues, 930 (Cogent customers) + 645 (TATA customers)

It also seems that the same archive has a guess at how old you are too, Discord has gotten this entirely wrong, except one time.

{
  "user_id": "282657081457115136",
  "predicted_age": "35+",
  "probability": 0.7547529339790344,
  "prob_13_17": 0.0005852651665918529,
  "prob_18_24": 0.014580278657376766,
  "prob_25_34": 0.23008151352405548,
  "prob_35_over": 0.7547529339790344,
  "model_version": "2024-03-20T00:00:00.000000Z",
  "day_pt": "2024-03-27 00:00:00 UTC"
}

A graph showing probability over time for age, this graph shows discord thinks that I am 35+, when I am actually 29

Ha! The Discord GDPR/Data Export thing reveals that it's running models to figure out what gender you are. If you go to /activity/analytics/events-*.json and grep for predicted_gender you get something like:

{
  "user_id": "282657081457115136",
  "predicted_gender": "male",
  "probability": 0.8413839340209961,
  "prob_male": 0.8413839340209961,
  "prob_female": 0.11650349199771881,
  "prob_non_binary_gender_expansive": 0.04211260750889778,
  "model_version": "2024-05-08T00:00:00.000000Z",
  "day_pt": "2024-05-15 00:00:00 UTC"
}

Anyway, they seem to have this datapoint _over time_! Meaning you can make a graph of how male/female/NB you are according to discord, here is mine:

Nice day to take the PDU for a walk

A website CAPTCHA page cannot hurt you, apart from this one maybe:

Dammit. So many cheap EPYC CPU upgrades on UK eBay that I cannot use because Dell made the decision to blow the efuses on all EYPC CPUs to vendor lock them when they are first powered on. So the CPUs are only usable in dell motherboards.

There is a special place in hell etc etc

When the QinQ script is a bit too aggressive.

root@nikhef:~# ifdown enp1s0.801.10
Bringing down and removing the service VLAN interface enp1s0.801...
Bringing down the trunk interface enp1s0...
Shared connection to nikhef closed.

"enp1s0" was my sole transit interface... and this box was not on a PDU.... So I guess this is a "see you tomorrow when someone unplugs you"

One of the few times I've yelled "FUCK" at the top of my voice in a empty apartment...

I'm forever disappointed that windows phone did not survive, It had one of the better UX/UI stories that only now my Pixel 7 is equivalent to, while also just being decent hardware.

Though it still was windows through and through, demonstrated by the one time the phone crashed/rebooted/whatever during some activity and I got greeted with a classic "bootmgr" screen asking me to insert the windows installation disk into my phone...

A Nokia Lumia 920 displaying a black bootmgr screen asking saying that "Windows failed to start, a recent hardware or software change might have been the cause" -> "insert your windows installation disk and restart your computer" "Info: A required device isnt connected or cant be accessed"

Hmmm, Don't think it's supposed to do that on the lock screen password prompt

How do we collectively stop Google's NOC from replying to every single IX mailing list post thinking that people are talking to them directly. How do we teach them about mailing lists. Is such a thing possible????

Having never touched EVPN stuff (so far?, it's sort of out of my needs/desires) this is what a good % of IP networking conference talks sound like in my head:

(The original talk is actually interesting, even though I've never deployed EVPN)

Mentioned to some friends last night about the distinctive sounds (that are burned into my memory) of Windows IRDA, and I could not find a easy place to find the actual sounds themselves, so here you go, here is what trying to align your phones infrared port to your computer sounded like in 2004

TIL you can open MP4 (container) files in wireshark and it sorta works... I guess it's all "packets" at the end of the day
